In algebra, an Artin algebra is an algebra &Lambda over a commutative Artin ring R that is a finitely generated R module. They are named after Emil Artin . Every Artin algebra is an Artin ring. Dual and transpose There are several different dualities taking finitely generated modules over &Lambda to modules over the opposite algebra &Lambda sup op sup . If M is a left &Lambda module then the right &Lambda module M sup sup is defined to be Hom sub &Lambda sub M ,&Lambda . The dual D M of a left &Lambda module M is the right &Lambda module D M Hom sub R sub M , J , where J is the dualizing module of R , equal to the sum of the injective envelopes of the non isomorphic simple R modules or equivalently the injective envelope of R rad R . The dual of a left module over &Lambda does not depend on the choice of R up to isomorphism . The transpose Tr M of a left &Lambda module M is a right &Lambda module defined to be the cokernel of the map Q sup sup &rarr P sup sup , where P &rarr Q &rarr M &rarr 0 is a minimal projective presentation of M .

See Artin Schreier theorem for theory about real closed field s. In mathematics , Artin Schreier theory is a branch of Galois theory , and more specifically is a positive characteristic algebra characteristic analogue of Kummer theory , for Field extension extensions of degree equal to the characteristic p . It is named for Emil Artin and Otto Schreier . If K is a field mathematics field of characteristic p , a prime number , any polynomial of the form math X p X alpha, , math for math alpha math in K , is called an Artin Schreier polynomial . When math alpha math does not lie in the subset math y in K , , y x p x mbox for x in K math , this polynomial is irreducible in K X , and that its splitting field over K is a cyclic extension of K of degree p . This follows since for any root , the numbers i, for math 1 le i le p math , form all the roots by Fermat s little theorem so the splitting field is math K beta math which contains no proper subfields. Conversely, any Galois extension of K of degree p remember, p is equal to the characteristic of K is the splitting field of an Artin Schreier polynomial. This can be proved using additive counterparts of the methods involved in Kummer theory , such as Hilbert s theorem 90 and additive Galois cohomology . Artin Schreier extensions, as are called those arising from Artin Schreier polynomials, play a role in the theory of solvability by radicals , in characteristic p , representing one of the possible classes of extensions in a solvable chain. They also play a part in the theory of abelian varieties and their isogeny isogenies . In characteristic p , an isogeny of degree p of abelian varieties must, for their function fields, give either an Artin Schreier extension or a purely inseparable extension . There is an analogue of Artin Schreier theory which describes cyclic extensions in characteristic p of p power degree not just ... al.

In abstract algebra , the Artin Wedderburn theorem is a classification theorem for Semisimple algebra semisimple ring mathematics rings . The theorem states that an Artinian ring Artinian semisimple ring R is isomorphic to a Product of rings product of finitely many n sub i sub by n sub i sub matrix ring s over division ring s D sub i sub , for some integers n sub i sub , both of which are uniquely determined up to permutation of the index i . In particular, any simple ring simple left or right Artinian ring is isomorphic to an n by n matrix ring over a division ring D , where both n and D are uniquely determined. As a direct corollary, the Artin Wedderburn theorem implies that every simple ring that is finite dimensional over a division ring a simple algebra is a matrix ring . This is Joseph Wedderburn s original result. Emil Artin later generalized it to the case of Artinian rings. Note that if R is a finite dimensional simple algebra over a division ring E , D need not be contained in E . For example, matrix rings over the complex number s are finite dimensional simple algebras over the real number s. The Artin Wedderburn theorem reduces classifying simple rings over a division ring to classifying division rings that contain a given division ring. This in turn can be simplified The center algebra center of D must be a field mathematics field K. Therefore R is a K algebra, and itself has K as its center. A finite dimensional simple algebra R is thus a central simple algebra over K. Thus the Artin Wedderburn theorem reduces the problem of classifying finite dimensional central simple algebras to the problem of classifying division rings with given center.

In mathematics , the Artin&ndash Mazur zeta function , named after Michael Artin and Barry Mazur , is a tool for studying the iterated function s that occur in dynamical systems and fractals . It is defined as the formal power series math zeta f z exp sum n 1 infty textrm card left textrm Fix f n right frac z n n , math where Fix &fnof sup n sup is the set of Fixed point mathematics fixed point s of the n th iterate of an iterated function &fnof , and card Fix &fnof sup n sup is the cardinality of this set of fixed points. Note that the zeta function is defined only if the set of fixed points is finite. This definition is formal in that it does not always have a positive radius of convergence . The Artin&ndash Mazur zeta function is invariant under topological conjugation . The Milnor Thurston kneading theory Milnor&ndash Thurston theorem states that the Artin&ndash Mazur zeta function is the inverse of the kneading determinant of &fnof . Analogues The Artin&ndash Mazur zeta function is formally similar to the local zeta function , when a diffeomorphism on a compact manifold replaces the Frobenius mapping for an algebraic variety over a finite field . The Ihara zeta function of a graph can be interpreted as an example of the Artin&ndash Mazur zeta function.

In number theory , the Ankeny Artin Chowla congruence is a result published in 1953 by N. C. Ankeny , Emil Artin and S. Chowla . It concerns the class number number theory class number h of a real quadratic field of discriminant d 0. If the fundamental unit of the field is math varepsilon frac t u sqrt d 2 math with integers t and u , it expresses in another form math frac ht u pmod p math for any prime number p 2 that divides d . In case p 3 it states that math 2 mht over u equiv sum 0 k d chi k over k lfloor k p rfloor pmod p math where math m frac d p math and math chi math is the Dirichlet character for the quadratic field. For p 3 there is a factor 1 m multiplying the Sides of an equation LHS . Here math lfloor x rfloor math represents the floor function of x . A related result is that if p is congruent to one mod four, then math u over t h equiv B p 1 2 pmod p math where B sub n sub is the n th Bernoulli number . There are some generalisations of these basic results, in the papers of the authors. References N. C. Ankeny, E.

In mathematics , the Artin approximation theorem is a fundamental result of Michael Artin in deformation theory which implies that formal power series with coefficients in a field mathematics field k are well approximated by the algebraic function s on k . Statement of the theorem Let x x sub 1 sub , , x sub n sub denote a collection of n indeterminate variable indeterminate s, k nowiki x nowiki the ring mathematics ring of formal power series with indeterminates x over a field k , and y y sub 1 sub , , y sub m sub a different set of indeterminates. Let f x , y 0 be a system of polynomial equation s in k x , y , and c a positive integer . Then given a formal power series solution x k nowiki x nowiki there is an algebraic solution y x consisting of algebraic function s such that x y x mod x sup c sup . Discussion Given any desired positive integer c , this theorem shows that one can find an algebraic solution approximating a formal power series solution up to the degree specified by c . This leads to theorems that deduce the existence of certain formal moduli space s of deformations as scheme mathematics scheme s. References Artin, Michael. Algebraic Spaces .

In mathematics, the Artin Hasse exponential , named after Emil Artin and Helmut Hasse , is the power series given by math E p x exp left x frac x p p frac x p 2 p 2 frac x p 3 p 3 cdots right . math Properties The coefficients are p integral in other words, their denominators are not divisible by p . This follows from Dwork s lemma , which says that a power series f x 1 ... with rational coefficients has p integral coefficients if and only if f x sup p sup f x sup p sup &equiv 1 mod p . The coefficient of x sup n sup of n E sub p sub x is the number of elements of the symmetric group on n points of order a power of p . This gives another proof that the coefficients are p integral, using the fact that in a finite group of order divisible by d the number of elements of order dividing d is also divisible by d . It can be written as the infinite product math E p x prod p,n 1 1 x n mu n n . math The function &mu is the M bius function . This resembles the exponential series, in the sense that taking this product over all n rather than only n prime to p is an infinite product which converges in the ring of formal power series to the exponential series.
