T theory is a branch of discrete mathematics dealing with analysis of tree graph theory tree s and discrete metric spaces . General history As per Andreas Dress , T theory originated from a question raised by Manfred Eigen , a recipient of the Nobel Prize in Chemistry , in the late seventies. He was trying to fit twenty distinct transfer RNA t RNA molecule s of the Escherichia coli E. Coli bacterium into a tree. One of the most important concepts of T theory is the tight span of a metric space. If X is a metric space, the tight span T X of X is, up to isomorphism, the unique minimal injective metric space that contains X . John Isbell was the first to discover the tight span in 1964, which he called the injective envelope . Dress independently constructed the same construct, which he called the tight span. Application areas Phylogenetic analysis, which is used to create phylogenetic tree s. Online algorithm s k server problem k server problem Recent developments Bernd Sturmfels , Professor of Mathematics and Computer Science at University of California, Berkeley Berkeley , and Josephine Yu classified six point metrics using T theory.

One source date May 2010 The term theorytheory or theorytheory is a theory in cognitive development that children construct theories to explain everything they experience. ref name KSB The developing person through childhood and adolescence , Kathleen Stassen Berger, 2005, Chapter 9 The Play Years Cognitive Development , p.262 of 608 pages , web http books.google.com books?id fCfiqDisIH8C&pg PA262 &lpg PA262 Books Google IH8C . ref According to theorytheory, the best idea and explanation of mental processes ref name KSB in young children is that humans always seek reasons, causes, and underlying principles for what they experience. The essential idea of theorytheory is that children do not want simple logical definitions but, rather, seek fuller explanations of various things, especially of those that involve them. small ref name KSB small The term originated in the 20th century, and the concept is also referred to as model theory .

Dependency theory is a subfield of database theory which studies implication and optimization problems related to logical constraints, commonly called dependencies, on databases. The best known class of such dependencies are functional dependencies , which form the foundation of candidate key keys on database relations. Another important class of dependencies are the multivalued dependency multivalued dependencies . A key algorithm in dependency theory is the Chase algorithm Chase , and much of the theory is devoted to its study. database stub Category Database theory Category Database constraints ... more details
