Variational Methods for a Fractional Dirichlet Problem Involving Jumarie’s Derivative
(Hindawi Publishing Corporation, 2015-07-08)We investigate a fractional Dirichlet problem involving Jumarie’s derivative. Using some variational methods a theorem on the existence and uniqueness of a solution to such problem is proved. In the proof of the main ... -
Cloning by positive maps in von Neumann algebras
(Springer Basel, 2014-06-19)We investigate cloning in the general operator algebra framework in arbitrary dimension assuming only positivity instead of strong positivity of the cloning operation, generalizing thus results obtained so far under that ... -
Monotone iterative procedure and systems of a finite number of nonlinear fractional differential equations
(Springer International Publishing, 2015-06-03)The aim of the paper is to present a nontrivial and natural extension of the comparison result and the monotone iterative procedure based on upper and lower solutions, which were recently established in (Wang et al. in ... -
The Łojasiewicz exponent over a field of arbitrary characteristic
(Springer Verlag, 2015-01-13)Let K be an algebraically closed field and let K((XQ)) denote the field of generalized series with coefficients in K. We propose definitions of the local Łojasiewicz exponent of F = ( f1, . . . , fm) ∈ K[[X, Y ]]m as ... -
Multivalued SK-contractions with respect to b-generalized pseudodistances
(Springer Basel, 2015-04-09)A new class of multivalued non-self-mappings, called SK-contractions with respect to b-generalized pseudodistances, is introduced and used to investigate the existence of best proximity points by using an appropriate ... -
Entropy of Quantum Measurement
(MDPI, 2015-03-12)A notion of entropy of a normal state on a finite von Neumann algebra in Segal’s sense is considered, and its superadditivity is proven together with a necessary and sufficient condition for its additivity. Bounds on the ... -
Optymalizacja wektorowa w przestrzeniach częściowo uporządkowanych przez stożki wielościenne
(2015)W rozprawie rozważono zadania optymalizacyjne, w których minimalizacja funkcji celu jest przeprowadzana względem częściowego porządku wprowadzonego przez stożek wielościenny o niepustym wnętrzu. Przy wykorzystaniu górnych ... -
Submersje konforemne o włóknach umbilikalnych
(2015)Conformal submersions are natural generalisation of Riemannian submersions, introduced by O'Neill (1966). Using methods of Riemannian geometry, curvature relations between the domain and the image of such submersion were ... -
Sufficient optimality criteria and duality for multiobjective variational control problems with G-type I objective and constraint functions
(Springer, 2014-06-05)In the paper, we introduce the concepts of G-type I and generalized G-type I functions for a new class of nonconvex multiobjective variational control problems. For such nonconvex vector optimization problems, we prove ... -
Stability of Nonlinear Dirichlet BVPs Governed by Fractional Laplacian
Bors, Dorota
(Hindawi Publishing Corporation, 2014-03-02)
We consider a class of partial differential equations with the fractional Laplacian and the homogeneous Dirichlet boundary data. Some sufficient condition under which the solutions of the equations considered depend ... -
Hausdorff quasi-distances, periodic and fixed points for Nadler type set-valued contractions in quasi-gauge spaces
(Springer, 2014-12-05)In a quasi-gauge space (X,P) with quasi-gauge , using the left (right) -families of generalized quasi-pseudodistances on X (-families on X generalize quasi-gauge ), the left (right) quasi-distances DL−Jη ( DR−Jη) of Hausdorff ... -
New generalized fuzzy metrics and fixed point theorem in fuzzy metric space
(Springer, 2014-12-08)In this paper, in fuzzy metric spaces (in the sense of Kramosil and Michalek (Kibernetika 11:336-344, 1957)) we introduce the concept of a generalized fuzzy metric which is the extension of a fuzzy metric. First, inspired ... -
On best proximity points for set-valued contractions of Nadler type with respect to b-generalized pseudodistances in b-metric spaces
(Springer, 2014-02-14)In this paper, in b-metric space, we introduce the concept of b-generalized pseudodistance which is an extension of the b-metric. Next, inspired by the ideas of Nadler (Pac. J. Math. 30:475-488, 1969) and Abkar and Gabeleh ... -
State Determination and Sufficiency of Observables
(Springer, 2013-05-19)Informational completeness and the possibility of state distinction and determination are among the more important issues of quantum statistics. We use spectral and semispectral (POV) measures to analyse these questions. ... -
Quantum Sufficiency in the Operator Algebra Framework
(Springer, 2013-08-01)The paper is devoted to the investigation of the notion of sufficiency in quantum statistics. Three kinds of this notion are considered: plain sufficiency (called simply: sufficiency), Petz’s sufficiency, and Umegaki’s ... -
