MethodsX, 2023 We consider two-parameter singularly perturbed problems of reaction-convection-diffusion type in one dimension. The convection coefficient and source term are discontinuous at a point in the domain.

Frontiers in Applied Mathematics and Statistics, 2022 Despite the availability of an abundant literature on singularly perturbed problems, interest toward non-linear problems has been limited. In particular, parameter-uniform methods for singularly perturbed semilinear problems are quasi-non-existent.

Uniform convergence rates and uniform adaptive estimation in mixtures of regressions [PDF]
, 2018 In this thesis, we develop theoretical tools to examine estimators in non-parametric regression models in regard of uniform convergence rates and uniform adaptivity with respect to the smoothness of the parameter functions.

Uniform density estimates and Γ-convergence for the Alt-Phillips functional of negative powers
Mathematics in Engineering, 2023 We obtain density estimates for the free boundaries of minimizers $ u \ge 0 $ of the Alt-Phillips functional involving negative power potentials $ \int_\Omega \left(|\nabla u|^2 + u^{-\gamma} \chi_{\{u>0\}}\right) \, dx, \quad \quad \gamma \in (

Singularly perturbed robin type boundary value problems with discontinuous source term in geophysical fluid dynamics [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2021 Singularly perturbed robin type boundary value problems with discontinuous source terms applicable in geophysical fluid are considered. Due to the discontinuity, interior layers appear in the solution.

On the Durrmeyer variant of q-Bernstein operators based on the shape parameter λ
Journal of Inequalities and Applications, 2023 In this work, we consider several approximation properties of a Durrmeyer variant of q-Bernstein operators based on Bézier basis with the shape parameter λ ∈ [ − 1 , 1 ] $\lambda \in[ -1,1]$ .
