Categorical 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...
متن کاملCounting racks of order n
A rack on [n] can be thought of as a set of maps (fx)x∈[n], where each fx is a permutation of [n] such that f(x)fy = f −1 y fxfy for all x and y. In 2013, Blackburn showed that the number of isomorphism classes of racks on [n] is at least 2(1/4−o(1))n 2 and at most 2(c+o(1))n 2 , where c ≈ 1.557; in this paper we improve the upper bound to 2(1/4+o(1))n 2 , matching the lower bound. The proof in...
متن کاملCategorical Properties of Soft Sets
The present study investigates some novel categorical properties of soft sets. By combining categorical theory with soft set theory, a categorical framework of soft set theory is established. It is proved that the category SFun of soft sets and soft functions has equalizers, finite products, pullbacks, and exponential properties. It is worth mentioning that we find that SFun is both a topologic...
متن کاملCategorical Properties of Logical Frameworks
In this paper we define a logical framework, called λTT , that is well-suited for semantic analysis. We introduce the notion of a fibration L1 : T1 −→ C1 being internally definable in a fibration L2 : T2 −→ C2. This notion amounts to distinguishing an internal category L in L2 and relating L1 to the externalization of L through a pullback. When both L1 and L2 are term models of typed calculi L ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
