Finally, we consider whether the modular invariance property is satisfied or not, namely whether there exists a diagonal matrix T satisfying the condition (ST)3 = S 2.

Augustine O'Keefe's research lies at the intersection of commutative algebra, combinatorics, and topology. In particular, she is interested in monomial and toric binomial ideals defined from combinatorial objects such as discrete graphs and simplicial complexes. The overarching goal is then to get a handle on the algebraic structure of the ...Combinatorics on words has arisen independently within several branches of mathematics, for instance number theory, group theory and probability, and appears frequently in problems related to theoretical computer science.

Combinatorics is the study of finite structures.

Submission historyHere we present the usual definition of what a linear program is: it is defined by a matrix A: R m ↦ R n, along with two vectors b, c ∈ R n. Solving a linear program is searching for a vector x maximizing an objective function and satisfying a set of constraints, i.e. c t x = max x ′ such that A x ′ ≤ b c t x ′. portable bathtub nearby Combinatorics.
