In this paper, a two- stage stochastic fully fuzzy linear programming is developed for a management problem in terms of water resources allocations to illustrate the applicability of a proposed approach. A proposed approach converts the problem into a triple- objective problem an...

We present a special B-spline tight frame and use it to introduce our numerical approximation method. We apply our method to investigate Gibbs effects and illustrate some features of the associated framelet expansion. It is shown that Gibbs effects occurs in the framelet expansio...

We construct injective hulls and projective covers in categories of generalized uniform hypergraphs which generalizes the constructions in the category of quivers and the category of undirected graphs. While the constructions are not functorial, they are “sub-functorial”, meaning...

The aim of this paper is as to study real (C1,C2)- Holder valuations on skew polynomials rings. Let D be a division ring, T be a variable over D,σ an endomorphism of D, δ a σ-derivation of D and R = D[T; σ; δ] the left skew polynomial ring over D. We show the set (HV alv(R),) of...
