Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach
Mathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4184-4197, 30 March 2026.ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

Weierstrass-type representations for timelike surfaces
Advanced Studies in Pure Mathematics, 2018 In this paper we give the Weierstrass-type representation for Lorentz conformal minimal surfaces in Minkowski 3-space that was derived by Konderak, and a new one for Lorentz conformal constant mean curvature 1 surfaces in anti de Sitter 3-space, using integrable systems techniques. As an application, we analyze their singularities. Finally, we describe

Diverse Soliton Structures of Induced Curves in the Integrable Coupled Kuralay Equation
Advances in Mathematical PhysicsThis study explores the integrable coupled Kuralay equation, which is widely utilized to study the motion of induced curves. In fields such as ferromagnetic materials, nonlinear optics, and optical fibers, soliton solutions of the Kuralay equation have ...

Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2463-2473, 15 March 2026.ABSTRACT This paper proposes a novel extension of the classical cobweb price model by incorporating behavioral inventory responses through an anticipatory mini‐storage mechanism. In many real‐world commodity markets, persistent price oscillations occur even when classical stability conditions are theoretically satisfied, an inconsistency traditional ...

Dynamic Optimal Transport with Optimal Star‐Shaped Graphs
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT We study an optimal transport problem in a compact convex set Ω⊂Rd$\Omega \subset \mathbb {R}^d$ where bulk transport is coupled to dynamic optimal transport on a metric graph G=(V,E,l)$ \mathsf {G}= (\mathsf {V},\mathsf {E},l)$ which is embedded in Ω$\Omega$. We prove the existence of solutions for fixed graphs.

Generalizations of Weierstrass representation formula for surfaces in Minkowski space
, 2022 U radnji poopćavamo Weierstrassovu reprezentacijsku formulu na plohe u prostoru Minkowskog. Weierstrassova parametrizacija je lokalna konformna parametrizacija plohe kojom se svaka minimalna ploha u \(\mathbb{E}^3\) može reprezentirati parom \((f,g ...
