lowercase The g index is an index for quantifying scientific productivity based on publication record. It was suggested in 2006 by Leo Egghe . The index is calculated based on the distribution of citation s received by a given researcher s publications Given a set of articles ranked in decreasing order of the number of citations that they received, the g index is the unique largest number such that the top g articles received together at least g sup 2 sup citations. In simple terms, this means that an author that produces n articles is expected to have, on average, n citations for each of them, in to have a g index of n. In this way, it is similar to the hindex, with the difference that the number of citations per article is not explicit. The g index has been characterized in terms of three natural axioms by Woeginger 2008 . The simplest of these three axioms states that by moving citations from weaker articles to stronger articles, one s research index should not decrease. The g index is highly correlated with the hindex Serenko 2010 . However, these indices are conceptually distinct, and the g index attempts to address shortcomings of the hindex . Like the hindex , the g index is a natural number and thus lacks in discriminatory power. Therefore, Tol 2008 proposed a rational ... 2010 Tol also proposed a collective g index. Given a set of researchers ranked in decreasing order of their g index, the g sub 1 sub index is the unique largest number such that the top g sub 1 sub researchers have on average at least a g index of g sub 1 sub .

In mathematics , specifically group theory , the index of a subgroup H in a group G is the relative size of H in G equivalently, the number of copies cosets of H that fill up G . For example, if H has index 2 in G , then intuitively half of the elements of G lie in H . The index of H in G is usually denoted G H or nowiki nowiki G H nowiki nowiki . Formally, the index of H in G is defined as the number of coset s of H in G . The number of left cosets of H in G is always equal ... integer, as the example above shows. If G and H are finite group s, then the index of H in G is equal ... 1 sup of a subgroup H in G is equal to the index of the normalizer of H in G . If H is a subgroup of G , the index of the core group normal core of H satisfies the following inequality math G operatorname ... index below . As a corollary, if the index of H in G is 2, or for a finite group the lowest prime p that divides the order of G, then H is normal, as the index of its core must also be p, and thus H equals ... group cyclic subgroup of index 2, which is necessarily normal. Infinite index If H has an infinite number of cosets in G , then the index of H in G is said to be infinite. In this case, the index G H is actually a cardinal number . For example, the index of H in G may be countable set ... in G . Note that the index of H is at most the order of G, which is realized for the trivial subgroup, or in fact any subgroup H of infinite cardinality less than that of G. Finite index An infinite group G may have subgroups H of finite index for example, the even integers inside the group of integers . Such a subgroup always contains a normal subgroup N of G , also of finite index. In fact, if H ... .

Common methods used to determine site index are based on tree height, plant composition and the use of soil maps. Determining Site Index The most common of the methods used to determine site index is tree height. Determining site index is achieved by measuring and averaging the total height and age of trees found on that site. Height ... or harvest records. These values are then used on a graph or an equation called a site index curve. Determining site index from plant composition is often referred to as the indicator plant approach. Site index is determined from plant composition by the presence, abundance, and size of understory ... Avery In the United States, site index can be determined from soil maps provided by the Natural Resources Conservation Service NRCS . Soil surveys were conducted by the NRCS and site index was measured ... in overall height, and the stand age is determined to be 50 years old. To find site index from a site index curve, one would find age 50 along the x axis and then find convert 60 ft m along the y axis. Where these two points intersect one would find the nearest line, which represents the site index for that stand. An example of a site index equation is ln S ln H sub d sub b sub 1 sub A sup 1 sup A sub i sub sup 1 sup Where S is site index, A sub i sub is index age, H sub d sub is height of dominants and co dominants and A is stand age.

In chemical graph theory , the Wiener index also Wiener number is a topological index of a molecule , defined as the sum of the numbers of edge graph theory edge s in the shortest path s in a chemical graph between all pairs of non hydrogen atoms in a molecule . It was introduced by Harry Wiener in 1947. ref H. Wiener, Structural determination of paraffin boiling points , J. Am. Chem. Soc., 1947, 69 1 , 17 20. ref Wiener index may be calculated using the Floyd Warshall algorithm . Bojan Mohar and Toma Pisanski presented an efficient algorithm for computing the Wiener index of a tree. ref Bojan Mohar , Toma Pisanski , How to compute the Wiener index of a graph J. Math.

In quantum field theory and statistical mechanics , the Witten index at the inverse temperature is defined as a modification of the standard partition function math Tr 1 F e beta H math Note the 1 F 1 sup F sup operator, where F is the fermion number operator . This is what makes it different from the ordinary partition function mathematics partition function . In a supersymmetry supersymmetric theory, each nonzero energy eigenvalue contains an equal number of bosonic and fermionic states. Because of this, the Witten index is independent of the temperature and gives the number of zero energy bosonic vacuum state s minus the number of zero energy fermionic vacuum states. In particular, if supersymmetry breaking supersymmetry is spontaneously broken then there are no zero energy ground states and so the Witten index is equal to zero. The Witten index of a supersymmetric field theory is an example of a quasi topological quantity, which is a quantity that depends only on F term s and not on D term s in the Lagrangian . A more refined invariant in 2 dimensional theories, constructing using only the right moving part of the fermion number operator together with a 2 parameter family of variations, is the Genus of a multiplicative sequence elliptic genus .
