A note on the dependence of solutions on functional parameters for nonlinear sturmliouville problems
(AGH University of Science and Technology Press, 2014)We deal with the existence and the continuous dependence of solutions on functional parameters for boundary valued problems containing the SturmLiouville equation. We apply these result to prove the existence of at least ... 
Best Proximity Point Theorem in QuasiPseudometric Spaces
(Hindawi, 2016)In quasipseudometric spaces (not necessarily sequentially complete), we continue the research on the quasigeneralized pseudodistances. We introduce the concepts of semiquasiclosed map and contraction of Nadler type with ... 
Cloning by positive maps in von Neumann algebras
(Springer Basel, 20140619)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 ...

Comparison of ultrasound image filtering methods by means of multivariable kurtosis
(International Society for Stereology & Image Analysis, 2017)Comparison of the quality of despeckled US medical images is complicated because there is no image of a human body that would be free of speckles and could serve as a reference. A number of various image metrics are ... 
Duality for multiobjective variational control problems with (Φ,ρ)invexity
(Springer, 20131129)In this paper, MondWeir and Wolfe type duals for multiobjective variational control problems are formulated. Several duality theorems are established relating efficient solutions of the primal and dual multiobjective ... 
Dynamic Processes, Fixed Points, Endpoints, Asymmetric Structures, and Investigations Related to Caristi, Nadler, and Banach in Uniform Spaces
(Hindawi Publishing Corporation, 2015)In uniform spaces (...) with symmetric structures determined by the Dfamilies of pseudometrics which define uniformity in these spaces, the new symmetric and asymmetric structures determined by the Jfamilies of generalized ... 
Dynamic programming approach to structural optimization problem – numerical algorithm
(AGH University of Science and Technology Press, 2014)In this paper a new shape optimization algorithm is presented. As a model application we consider state problems related to fluid mechanics, namely the NavierStokes equations for viscous incompressible fluids. The general ... 
Entropy of Quantum Measurement
(MDPI, 20150312)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 ... 
Fixed points of dynamic processes of setvalued Fcontractions and application to functional equations
(Springer International Publishing, 20150211)The article is a continuation of the investigations concerning Fcontractions which have been recently introduced in [Wardowski in Fixed Point Theory Appl. 2012:94,2012]. The authors extend the concept of Fcontractive ... 
Generalized gradients on Lie algebroids
(Springer Netherlands, 2013)Generalized O(n) gradients for connections on Lie algebroids are derived. 
Hausdorff quasidistances, periodic and fixed points for Nadler type setvalued contractions in quasigauge spaces
(Springer, 20141205)In a quasigauge space (X,P) with quasigauge , using the left (right) families of generalized quasipseudodistances on X (families on X generalize quasigauge ), the left (right) quasidistances DL−Jη ( DR−Jη) of Hausdorff ... 
Monotone iterative procedure and systems of a finite number of nonlinear fractional differential equations
(Springer International Publishing, 20150603)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 ... 
Multi PingPong and an Entropy Estimate in Groups
(De Gruyter, 2018)We provide an entropy estimate from below for a finitely generated group of transformation of a compact metric space which contains a pingpong game with several players located anywhere in the group. 
Multivalued SKcontractions with respect to bgeneralized pseudodistances
(Springer Basel, 20150409)A new class of multivalued nonselfmappings, called SKcontractions with respect to bgeneralized pseudodistances, is introduced and used to investigate the existence of best proximity points by using an appropriate ... 
New generalized fuzzy metrics and fixed point theorem in fuzzy metric space
(Springer, 20141208)In this paper, in fuzzy metric spaces (in the sense of Kramosil and Michalek (Kibernetika 11:336344, 1957)) we introduce the concept of a generalized fuzzy metric which is the extension of a fuzzy metric. First, inspired ... 
On a Nonsmooth Gauss–Newton Algorithms for Solving Nonlinear Complementarity Problems
(MDPI, 2020)In this paper, we propose a new version of the generalized damped Gauss–Newton method for solving nonlinear complementarity problems based on the transformation to the nonsmooth equation, which is equivalent to some ... 
On best proximity points for setvalued contractions of Nadler type with respect to bgeneralized pseudodistances in bmetric spaces
(Springer, 20140214)In this paper, in bmetric space, we introduce the concept of bgeneralized pseudodistance which is an extension of the bmetric. Next, inspired by the ideas of Nadler (Pac. J. Math. 30:475488, 1969) and Abkar and Gabeleh ... 
On conformal submersions with geodesic or minimal fibers
(Springer, 2020)We prove that every conformal submersion from a round sphere onto an Einstein manifold with fbers being geodesics is—up to an isometry—the Hopf fbration composed with a conformal difeomorphism of the complex projective ...

(Springer US, 20121023)In the paper the optimization problem described by some nonlinear hyperbolic equation being continuous counterpart of the FornasiniMarchesini model is considered. A theorem on the existence of at least one solution to ...
