On Factorizations of Smooth Nonnegative Matrix-values Functions and on Smooth Functions with Values in Polyhedra
We discuss the possibility to represent smooth nonnegative matrix-valued functions as finite linear combinations of fixed matrices with positive real-valued coefficients whose square roots are Lipschitz continuous. This issue is reduced to a similar problem for smooth functions with values in a polyhedron. 1. Motivation One of the main goals of the article is to understand what kind of optimal ...
متن کاملdeterminant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
15 صفحه اولOn Analytic Functions with Positive Imaginary Parts
systems, each of which violates the like-numbered postulate and satisfies all the other postulates of the set. These examples are all arithmetic systems, the elements being the numbers 0 and 1. The symbol/(a , b) (mod 2) in an arithmetic system denotes the least positive residue modulo 2 obtained from /(a , b) by rejecting multiples of 2. The operations + and X are to be interpreted as the oper...
متن کاملOn characterizations of the fully rational fuzzy choice functions
In the present paper, we introduce the fuzzy Nehring axiom, fuzzy Sen axiom and weaker form of the weak fuzzycongruence axiom. We establish interrelations between these axioms and their relation with fuzzy Chernoff axiom. Weexpress full rationality of a fuzzy choice function using these axioms along with the fuzzy Chernoff axiom.
متن کاملRational values of Weierstrass zeta functions
We answer a question of Masser by showing that for the Weierstrass zeta function ζ corresponding to a given lattice Λ, the density of algebraic points of absolute multiplicative height bounded by T and degree bounded by k lying on the graph of ζ, restricted to an appropriate domain, does not exceed c(log T ), for an effective constant c > 0 depending on k and on Λ. Using different methods, we a...
