Let a family of monomorphisms in the category A To study mathematical notions in a category A, such as injectivity, tensor products, flatness, with respect to a class M of its (mono)morphisms, one should know some of the categorical properties of the pair (A ,M ). In this paper we take A to be thecategory Pos-S of S-partially ordered sets and to be a particular class o...
In this paper, a concept of generalized weakly contraction mappings in partially ordered fuzzy metric spaces is introduced and coincidence point theorems on partially ordered fuzzy metric spaces are proved. Also, as the corollary of these theorems, some common fixed point theorems on partially ordered fuzzy metric spaces are presented.
In recitals of this paper there we will be repeated the definitions and main results mentioned 1n [15] without proofs. The definition of the multioperation on partially ordered carrier set in this papers is idempotent, commutative but not associative operation. In the opening part of this article there we repeat fundamental definitions and some theorems without proofs. In the next part of this ...
We continue the study [2] on sheaves of rings on finite posets. We present examples where the ring of global sections coincide with toric faces rings, quotients of a polynomial ring by a monomial ideal and algebras with straightening laws. We prove a rank-selection theorem which generalizes the well-known rank-selection theorem of Stanley–Reisner rings. Finally, we determine an explicit present...
