Pointwise vanishing velocity helicity of a flow does not preclude magnetic field generation

Alexander Andrievsky, Roman Chertovskih, Vladislav Zheligovsky

Pointwise zero velocity helicity density is shown not to prevent steady flows from acting as kinematic dynamos. We present numerical evidences that such flows can generate both sma…

An iterative approach to monochromatic phaseless inverse scattering

Alexey Agaltsov, Thorsten Hohage, Roman Novikov

This paper is concerned with the inverse problem to recover a compactly supported Schr{ö}dinger potential given the differential scattering cross section, i.e. the modulus, but not…

Integrated fractional Brownian motion: persistence probabilities and their estimates

G. Molchan

The problem is a log-asymptotics of the probability that the Integrated fractional Brownian motion of index 0<H<1 does not exceed a fixed level during long time. For the growing ti…

Moutard transform for the conductivity equation

P. G. Grinevich, R. G. Novikov

We construct Darboux-Moutard type transforms for the two-dimensional conductivity equation. This result continues our recent studies of Darboux-Moutard type transforms for generali…
