Study of the Hypergeometric Equation via Data Driven Koopman-EDMD Theory
Axioms, 2023 We consider a data-driven method, which combines Koopman operator theory with Extended Dynamic Mode Decomposition. We apply this method to the hypergeometric equation which is the Fuchsian equation with three regular singular points.

Spectral approximations of strongly degenerate elliptic differential operators
Karpatsʹkì Matematičnì Publìkacìï, 2019 We establish analytical estimates of spectral approximations errors for strongly degenerate elliptic differential operators in the Lebesgue space $L_q(\Omega)$ on a bounded domain $\Omega$.

Moduli stabilization in asymptotic flux compactifications
Journal of High Energy Physics, 2022 We present a novel strategy to systematically study complex-structure moduli stabilization in Type IIB and F-theory flux compactifications. In particular, we determine vacua in any asymptotic regime of the complex-structure moduli space by exploiting ...

Electromagnetic Scattering by Bianisotropic Spheres
Applied Sciences, 2023 Electromagnetic fields in bulk bianisotropic media contain plane waves whose k-vectors can be found using the method of the index of refraction’s operator and belong to the Fresnel wave surfaces that fall into one of the five hyperbolic classes of the ...

A Survey of Results on the Limit -Bernstein Operator
Journal of Applied Mathematics, 2013 The limit -Bernstein operator emerges naturally as a modification of the Szász-Mirakyan operator related to the Euler distribution, which is used in the -boson theory to describe the energy distribution in a -analogue of the coherent state.

Covering-Based Rough Sets on Eulerian Matroids
Journal of Applied Mathematics, 2013 Rough set theory is an efficient and essential tool for dealing with vagueness and granularity in information systems. Covering-based rough set theory is proposed as a significant generalization of classical rough sets.

Dimension-8 SMEFT analysis of minimal scalar field extensions of the Standard Model
Journal of High Energy Physics, 2023 We analyze the constraints obtainable from present data using the Standard Model Effective Field Theory (SMEFT) on extensions of the Standard Model with additional electroweak singlet or triplet scalar fields.

On the convergence of the combination technique [PDF]
, 2013 Sparse tensor product spaces provide an efficient tool todiscretize higher dimensional operator equations. The direct Galerkin method in such ansatz spaces may employ hierarchical bases, interpolets, wavelets or multilevel frames. Besides, an alternative

Inequalities for some iterated linear operators and their applications in approximation theory
Journal of Numerical Analysis and Approximation Theory, 2001 Some inequalities for the ”derivatives” of iterated linear operators will be presented, which will be applied for the investigation of degrees of approximation. Thus, with the application of the Laplacian we improve some classical results concerning the Jackson type estimate, the inverse theorem as well as the saturation ...

Matroidal Structure of Generalized Rough Sets Based on Tolerance Relations
The Scientific World Journal, 2014 Rough set theory provides an effective tool to deal with uncertain, granular, and incomplete knowledge in information systems. Matroid theory generalizes the linear independence in vector spaces and has many applications in diverse fields, such as ...
