The size of a stratifying system can be arbitrarily large

نویسندگان

چکیده

In this short note we construct two families of examples large stratifying systems in module categories algebras. The first consist on infinite size the category an algebra A. second family show that a finite system dimensional A can be arbitrarily comparison to number isomorphism classes simple A-modules. We both are built using well-established results higher homological algebra.

A large population size can be unhelpful in evolutionary algorithms

The utilization of populations is one of the most important features of evolutionary algorithms (EAs). There have been many studies analyzing the impact of different population sizes on the performance of EAs. However, most of such studies are based computational experiments, except for a few cases. The common wisdom so far appears to be that a large population would increase the population div...

THE p-PART OF TATE-SHAFAREVICH GROUPS OF ELLIPTIC CURVES CAN BE ARBITRARILY LARGE

In this paper it is shown that for every prime p > 5 the dimension of the p-torsion in the Tate-Shafarevich group of E/K can be arbitrarily large, where E is an elliptic curve defined over a number field K, with [K : Q] bounded by a constant depending only on p. From this we deduce that the dimension of the p-torsion in the Tate-Shafarevich group of A/Q can be arbitrarily large, where A is an a...

Fuzzy implication can be arbitrarily complicated: A theorem

| In fuzzy logic, there are several methods of representing implication in terms of &, _, and :; in particular, explicit representations deene a class of S implications, implicit representations deene a class of R implications. Some reasonable implication operations have been proposed, such as Yager's a b , that are diicult to represent as S or R implications. For such operations, a new class o...

787 The p - part of Tate - Shafarevich groups of elliptic curves can be arbitrarily large par REMKE KLOOSTERMAN

In this paper we show that for every prime p ~ 5 the dimension of the p-torsion in the Tate-Shafarevich group of E/K can be arbitrarily large, where E is an elliptic curve defined over a number field K, with [K : Q] bounded by a constant depending only on p. From this we deduce that the dimension of the ptorsion in the Tate-Shafarevich group of A/Q can be arbitrarily large, where A is an abelia...
