$C^{1,\alpha}$ regularity for elliptic equations with the general nonstandard growth conditions [PDF]
Mathematica BohemicaWe study elliptic equations with the general nonstandard growth conditions involving Lebesgue measurable functions on $\Omega$. We prove the global $C^{1, \alpha}$ regularity of bounded weak solutions of these equations with the Dirichlet boundary ...

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In the present investigation, a mathematical model with vaccination, treatment, and environmental impact under real data is presented. Initially, we present the model without any interventions, followed by an examination of its equilibrium points.

Interaction of Dirac δ$$ \delta $$‐Waves in the Inviscid Levine and Sleeman Chemotaxis Model
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This article investigates interactions of δ$$ \delta $$‐shock waves in the inviscid Levine and Sleeman chemotaxis model ut−λ(uv)x=0$$ {u}_t-\lambda {(uv)}_x=0 $$, vt−ux=0$$ {v}_t-{u}_x=0 $$. The analysis employs a distributional product and a solution concept that extends the classical solution concept.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We study eigenvalue problems for the de Rham complex on varying three‐dimensional domains. Our analysis includes the Helmholtz equation as well as the Maxwell system with mixed boundary conditions and non‐constant coefficients. We provide Hadamard‐type formulas for the shape derivatives under weak regularity assumptions on the domain and its ...

Conditional Generative Modeling for Enhanced Credit Risk Management in Supply Chain Finance
Naval Research Logistics (NRL), EarlyView.ABSTRACT The rapid expansion of cross‐border e‐commerce (CBEC) has created significant opportunities for small‐ and medium‐sized sellers, yet financing remains a critical challenge due to their limited credit histories. Third‐party logistics (3PL)‐led supply chain finance (SCF) has emerged as a promising solution, leveraging in‐transit inventory as ...

On a Lebesgue constant of interpolation rational process at the Chebyshev – Markov nodes
Журнал Белорусского государственного университета: Математика, информатика, 2019 In the present paper estimate of a Lebesgue constant of the interpolation rational Lagrange process on the segment [−1 ,1] at the Chebyshev – Markov cosine fractions nodes is considered.

A priori estimates of global solutions of superlinear parabolic systems
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We consider the parabolic system $ u_{t}-\Delta u = u^{r}v^{p}$, $v_{t}-\Delta v = u^{q}v^{s}$ in $\Omega\times(0,\infty)$, complemented by the homogeneous Dirichlet boundary conditions and the initial conditions $(u,v)(\cdot,0) = (u_{0},v_{0})$ in ...
