Caratheodory perturbation of a second-order differential inclusion with constraints
Electronic Journal of Differential Equations, 2005 We prove the existence of local solutions for the second-order viability problem $$ ddot{x}(t) in f(t,x(t),dot{x}(t))+F(x(t),dot{x}(t)),quad x(t)in K. $$ Here $K$ is a closed subset of $mathbb{R}^{n}$, $F$ is an upper semicontinuous multifunction with ...

Bregman f-Projection Operator with Applications to Variational Inequalities in Banach Spaces
Abstract and Applied Analysis, 2014 Using Bregman functions, we introduce the new concept of Bregman generalized f-projection operator ProjCf, g:E*→C, where E is a reflexive Banach space with dual space E*; f: E→ℝ∪+∞ is a proper, convex, lower semicontinuous and bounded from below function;

From set-valued dynamical processes to fractals [PDF]
Opuscula MathematicaWe present a general theory of topological semiattractors and attractors for set-valued semigroups. Our results extend and unify those previously obtained by Lasota and Myjak.

A Few Notes on Formal Balls [PDF]
Logical Methods in Computer Science, 2017 Using the notion of formal ball, we present a few new results in the theory of quasi-metric spaces. With no specific order: every continuous Yoneda-complete quasi-metric space is sober and convergence Choquet-complete hence Baire in its $d$-Scott ...

On the lower semicontinuity of supremal functional under differential constraints [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2015 Given \(\Omega\) a bounded open subset of \({\mathbb R}^N\), \(V \in L^{\infty}(\Omega; {\mathbb M}^{d \times N})\), where \({\mathbb M}^{d \times N}\) is the space of \(d \times N\) matrices with real coefficients, and a partial differential operator \[ {\mathcal A} V := \sum_{i = 1}^N A^{(i)} \frac{\partial V}{\partial x_i}, \, \qquad V : \Omega \to {

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances
Computer Graphics Forum, EarlyView.We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Enlargements of Monotone Operators Determined by Representing Function
Journal of Mathematical Extension, 2012 In this paper, we study a new enlargement of subdifferential for any proper lower semicontinuous function. We know that ε-subdifferential of any proper lower semicontinuous function is an enlargement of its subfifferential and any point from the graph

A generalization of Ekeland’s variational principle by using the τ-distance with its applications
Journal of Inequalities and Applications, 2017 In this paper, a new version of Ekeland’s variational principle by using the concept of τ-distance is proved and, by applying it, an approximate minimization theorem is stated.

Empirical‐Process Limit Theory and Filter Approximation Bounds for Score‐Driven Time Series Models
Journal of Time Series Analysis, EarlyView.ABSTRACT This article examines the filtering and approximation‐theoretic properties of score‐driven time series models. Under specific Lipschitz‐type and tail conditions, new results are derived, leading to maximal and deviation inequalities for the filtering approximation error using empirical process theory.

On Two Iterative Methods for Mixed Monotone Variational Inequalities
Fixed Point Theory and Applications, 2010 A mixed monotone variational inequality (MMVI) problem in a Hilbert space H is formulated to find a point u∗∈H such that 〈Tu∗,v−u∗〉+φ(v)−φ(u∗)≥0 for all v∈H ...
