On graph equivalences preserved under extensions
Let G be the set of finite graphs whose vertices belong to some fixed countable set, and let ≡ be an equivalence relation on G. By the strengthening of ≡ we mean an equivalence relation ≡s such that G ≡s H , where G,H ∈ G, if for every F ∈ G, G ∪ F ≡ H ∪ F . The most important case that we study in this paper concerns equivalence relations defined by graph properties. We write G ≡ H , where Φ i...
متن کاملCategory equivalences involving graded modules over path algebras of quivers
Let Q be a finite quiver with vertex set I and arrow set Q1, k a field, and k Q its path algebra with its standard grading. This paper proves some category equivalences involving the quotient category QGr(k Q) := Gr(k Q)/Fdim(k Q) of graded k Q-modules modulo those that are the sum of their finite dimensional submodules, namely QGr(k Q) ≡ ModS(Q) ≡ GrL(Q) ≡ ModL(Q◦)0 ≡ QGr(k Q (n)). Here S(Q) =...
متن کاملIdempotent Residuated Structures: Some Category Equivalences and Their Applications
This paper concerns residuated lattice-ordered idempotent commutative monoids that are subdirect products of chains. An algebra of this kind is a generalized Sugihara monoid (GSM) if it is generated by the lower bounds of the monoid identity; it is a Sugihara monoid if it has a compatible involution ¬. Our main theorem establishes a category equivalence between GSMs and relative Stone algebras ...
متن کاملAre Vortex Numbers Preserved?
We study noncommutative vortex solutions that minimize the action functional of the Abelian Higgs model in 2-dimensional noncommutative Euclidean space. We first consider vortex solutions which are deformed from solutions defined on commutative Euclidean space to the noncommutative one. We construct solutions whose vortex numbers are unchanged under the noncommutative deformation. Another class...
متن کاملAre Decomposition Slices Clones?
When computing program slices on all variables in a system, we observed that many of these slices are the same. This leads to the question: Are we looking at software clones? We discuss the genesis of this phenomena and present some of the data observations that led to the question. The answer to our query is not immediately clear. We end by presenting arguments both pro and con. Supporting the...
