In this study, some (fuzzy) filters of a Sheffer stroke BL-algebra and its properties are presented. To show relationship between filter fuzzy BL-algebra, we prove that f is (ultra) C if only fp either empty or for each p ∈ [0, 1], it satisfied = f(1) the characteristic function nonempty subset BL-algebra.

As part of a larger study of student understanding of concepts in linear algebra, we interviewed 10 university linear algebra students as to their conceptions of functions from high school algebra and linear transformation from their study of linear algebra. An overarching goal of this study was to examine how linear algebra students see linear transformation as related to high school function....

We consider variational (density functional) models of fluids confined in parallelplate geometries (with walls situated in the planes z = 0 and z = L respectively) and focus on the structure of the pair correlation function G(r1, r2). We show that for local variational models there exist two non-trivial identities relating both the transverse Fourier transform G(zμ, zν ; q) and the zeroth momen...

Let G be a reductive connected linear algebraic group over an algebraically closed field of positive characteristic and let g be its Lie algebra. First we extend a well-known result about the Picard group of a semisimple group to reductive groups. Then we prove that, if the derived group is simply connected and g satisfies a mild condition, the algebra K[G] of regular functions on G that are in...

We study the range transformations 0p(/fD, Reß) and Op(/fD, B) for Banach function algebras A and B. As a special instance, the harmonicity of functions in Op(/fD, Re A) for a nontrivial function algebra A is established and is compared with previous investigations of Op( An, A) and Op((Re/l);, (Re/1)) for an interval /. In §2 we present some results on Op(AD, B) and use them to show that funct...

1.1 The main result. Given a map f : K → L of pointed CW complexes, let homf (K,L) denote the pointed space of pointed maps K → L, with f as the base point. Recall that a Πalgebra is a (≥ 1)-graded group with an action of the primary homotopy operations (for example, for any pointed topological space M there is a homotopy Π-algebra π∗M = {πiM}i=1). Given a map t : X → Y of Π-algebras, let homt(...

We consider functions of the form f : are only partially speciied. In general, f assigns to any output y i a nonempty set d 2 D of elements of E. If d = feg for some e 2 E, then y i has the value e. If d = E, then y i is a \complete don't care", i.e., is allowed to take on any value in E. In other cases, y i is a \limited don't care", allowed to take on any value in d. Moreover, the functions a...

first we show that the cosets of a fuzzy ideal μ in a bck-algebrax form another bck-algebra  x/μ (called the fuzzy quotient bck-algebra of x by μ). also we show thatx/μ is a fuzzy partition of x and we prove several some isomorphism theorems. moreover we prove that if the associated fuzzy similarity relation of a fuzzy partition p of a commutative bck-algebra iscompatible, then p is a fuzzy quo...
