The objective of this paper is to construct the accurate (say, to 11 decimal places) frequencies of the quasinormal modes of the five-dimensional Schwarzschild-Tangherlini black hole using three major techniques: the Hill determinant method, the cont

We study instability of unidirectional flows for the linearized 2D Navier–Stokes equations on the torus. Unidirectional flows are steady states whose vorticity is given by Fourier modes corresponding to a single vector $${\mathbf {p}} \in {\mathbb

We present positron scattering cross sections with C2H2 molecules obtained with the Method of Continued Fractions in the static plus correlation polarization level. The differential and integral cross sections are compared with available theoretical

We report an ab initio and model potential investigation of elastic and rotational excitation cross sections for positron impact with Li2 molecule in the energy range from 0.1 to 10.0 eV. The ab initio cross sections were calculated with the Schwinge

In this chapter we review the method of continued fractions to show its advantage and application. Convergence and its usefulness in working with irrational numbers, as well as converting a numerical series to continued fraction back and forth are th

We find a combinatorial interpretation of Shareshian and Wachs' $q$-binomial-Eulerian polynomials, which leads to an alternative proof of their $q$-$\gamma$-positivity using group actions. Motivated by the sign-balance identity of D\'esarm\'enien--Fo

We present a theoretical investigation on positron scattering by ${\text{N}}_{2}\text{O}$. Elastic differential and integral cross sections at both the static and static plus correlation-polarization levels of approximation are calculated and reporte

We report the rotational excitation of O2 molecule by positron impact for energies between 0.01 and 5.0 eV. The T-matrices were obtained by the method of continued fractions within the positron correlation-polarisation potential considering different

We extend recent work of Hatsuda on the computation of quasinormal mode frequencies via analytic continuation of bound state energies and Borel-Pade resummation of the Bender-Wu perturbation series to the case of charged fields in the background of R
