On Factorizable Semihypergroups

on semihypergroups and hypergroups

in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

On Pure Hyperradical in Semihypergroups

On Transitive Soft Sets over Semihypergroups

The aim of this paper is to initiate and investigate new soft sets over semihypergroups, named special soft sets and transitive soft sets and denoted by SH and TH , respectively. It is shown that TH = SH if and only if β = β ∗. We also introduce the derived semihypergroup from a special soft set and study some properties of this class of semihypergroups.

Prediction on widely factorizable signals

This article extends the solutions to the prediction problem for factorizable real random signals to the class of improper complex-valued random signals. For that, the concept of widely factorizable signals is introduced and several real examples of signals having a widely factorizable correlation function are presented. A widely linear processing is considered in the design of both linear and ...

Non-Factorizable Branes on the Torus

One of the important open problems in string theory is the lack of a systematic way to compute Yukawa couplings in generic situations. For the special case of tori wrapped by factorizable branes, that is branes wrapping a cycle in H1(T2,Z)3 ⊂ H3(T6,Z), instanton sums can be used to compute Yukawa couplings. But anything more complex ceases to be feasible at least in practice. Matrix factorizati...
