We define a discrete ω-sequence of index sets to be a sequence {θ An}n ≥ 0 of index sets of classes of recursively enumerable sets, such that for each n, θ An + 1 is an immediate successor of θ An in ...

Students can pursue a Master's Degree in Mathematical Sciences with an emphasis in discrete mathematics, pure mathematics, statistics, or computational and applied mathematics. Applicants are not ...

Recently the first and last authors defined a new graph characteristic called omega related to Euler characteristic to determine several topological and combinatorial properties of a given graph. This ...
