Creation and annihilation of point-potentials using Moutard-type transform in spectral variable

P. G. Grinevich, R. G. Novikov

We continue to develop the method for creation and annihilation of contour singularities in the --spectral data for the two-dimensional Schrödinger equation at fixed…

Computation of kinematic and magnetic -effect and eddy diffusivity tensors by Padé approximation

Sílvio M. A. Gama, Roman Chertovskih, Vladislav Zheligovsky

We present examples of Padé approximation of the -effect and eddy viscosity/diffusivity tensors in various flows. Expressions for the tensors derived in the framework of the sta…

Gusev's stochastic model for the seismic source: high-frequency behavior in the far zone

G. M. Molchan

This paper discusses local features in the source function that generate in the far zone simultaneously (a) a quadratic decay of the source spectrum and (b) the loss of radiation d…

Ramanujan's theorem and highest abundant numbers

Oleg R. Musin

In 1915, Ramanujan proved asymptotic inequalities for the sum of divisors function, assuming the Riemann hypothesis (RH). We consider a strong version of Ramanujan's theorem and de…

Asymptotic stability of robust heteroclinic networks

Olga Podvigina, Sofia B. S. D. Castro, Isabel S. Labouriau

We provide conditions guaranteeing that certain classes of robust heteroclinic networks are asymptotically stable. We study the asymptotic stability of ac-networks --- robust heter…
