Cohen-Macaulay Partially Ordered Sets with Pure Resolutions
1.1. Let V = {x1, x2, . . . , xv} be a finite set, called the vertex set, and 1 a simplicial complex on V . Thus 1 is a collection of subsets of V such that (i) {xi } ∈ 1 for every 1 ≤ i ≤ v and (ii) σ ∈ 1, τ ⊂ σ ⇒ τ ∈ 1. Each element σ of 1 is called a face of 1. Set d = max{#(σ ); σ ∈ 1}. Here #(σ ) is the cardinality of σ as a finite set. Then the dimension of 1 is defined by dim1 = d − 1. A...
متن کاملTripled partially ordered sets
In this paper, we introduce tripled partially ordered sets and monotone functions on tripled partiallyordered sets. Some basic properties on these new dened sets are studied and some examples forclarifying are given.
متن کاملPartially Ordered Sets
For example, thus far, I had the fortune to work intimately with nine (9) undergraduate students on research questions in the areas of computational algebra and algebraic geometry. I am directing two master’s students in their research for their theses at Sam Houston State University. All of these undergraduate students have enrolled in graduate programs around the country. Three have finished ...
متن کاملCategorical properties of regular partially ordered pure monomorphisms
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...
