A perverse sheaf is the topological counterpart of a differential equation with (regular) singularities. A perverse schober is "a category-valued perverse sheaf". It consists of monodromy... Daha fazla»

Commutative ring theorists have mainly concentrated in the study of Cohen-Macaulay rings and modules in the last fifty years. Understanding Cohen-Macaulay rings are important since they lie within ... Daha fazla»

Conze-Lesigne systems are abelian measure-preserving dynamical systems which are isomorphic to their second Host-Kra-Ziegler factors. These factors (and their versions of higher order) are rel... Daha fazla»

Let q be a prime power and Fq be the finite field with q elements. The explicit constructions of irreducible polynomials over Fq is one of the main problems in the arithmetic of finite fields which... Daha fazla»
