Weak Topologies on Toposes

Zeinab Khanjanzadeh, Ali Madanshekaf

This paper deals with the notion of weak Lawvere-Tierney topology on a topos. Our motivation to study such a notion is based on the observation that the composition of two Lawvere-…

Action preserving (weak) topologies on the category of presheaves

Zeinab Khanjanzadeh, Ali Madanshekaf

Let $C$ be a finitely complete small category. In this paper, first we construct two weak (Lawvere-Tierney) topologies on the category of presheaves. One of them is estab…

Lawvere-Tierney sheaves, factorization systems, sections and $j$ -essential monomorphisms in a topos

Zeinab Khanjanzadeh, Ali Madanshekaf

Let $j$ be a Lawvere-Tierney topology (a topology, for short) on an arbitrary topos $E$ , $B$ an object of $E$ , and $j_{B} = j \times 1_{B}$ the induced topology on t…

Weak Factorization System for Actions of Po-monoids on Posets

Farideh Farsad, Ali Madanshekaf

Let $S$ be a pomonoid. In this paper, {\bf Pos}- $S$ , the category of $S$ -posets and $S$ -poset maps, is considered. One of the main aims of this paper is to draw attention to the no…
