Numerical experiments with real data for estimating greenhouse gas fluxes in a region
Autor: M. V. Platonova, E. G. Klimova
Publikováno v: Interexpo GEO-Siberia. 4:132-137
This work is devoted to the problem of obtaining an estimate of methane emissions using satellite data and the results of mathematical modeling. To implement the algorithm, a variant of the local Kalman ensemble filter (LETKF) is used, which represen

On the Variance of the Particle Number of a Supercritical Branching Random Walk on Periodic Graphs
Autor: K. S. Ryadovkin, M. V. Platonova
Publikováno v: Journal of Mathematical Sciences. 258:897-911
We study the asymptotic behavior of the variance of the local particle number for a supercritical branching random walk with branching sources that are located periodically on Zd.

On One Limit Theorem Related to the Cauchy Problem Solution for the Schrödinger Equation with a Fractional Derivative Operator of Order $$ \upalpha\ \upepsilon \bigcup_{m=3}^{\infty}\left(m-1,m\right) $$
Autor: M. V. Platonova, S. V. Tsykin
Publikováno v: Journal of Mathematical Sciences. 258:912-919
We prove a limit theorem on the convergence of mathematical expectations of functionals of sums of independent random variables to the Cauchy problem solution for the nonstationary Schr¨odinger equation with a symmetric fractional derivative operato

Search for Fulde–Ferrell–Larkin–Ovchinnikov Superfluidity in an Ultracold Gas of Fermi Atoms
Autor: K. A. Karpov, S. S. Lukashov, V. A. Vinogradov, A. V. Turlapov, M. V. Platonova
Publikováno v: Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques. 15:1024-1028
In this paper, we discuss the search for the Fulde–Ferrell–Larkin–Ovchinnikov superfluid phase in an ultracold gas of Fermi atoms. A possible obstacle to obtaining this phase in known experiments is, first of all, the separation of the gas into

Probabilistic Approximation of the Solution of the Cauchy Problem for the Higher-Order Schrödinger Equation
Autor: M. V. Platonova, S. V. Tsykin
Publikováno v: Theory of Probability & Its Applications. 65:558-569
We propose two methods of approximation of the solution of the Cauchy problem for the higher-order Schrodinger equation. In the first method, the expectation of a functional of some random point fi...

Nonprobabilistic Analogs of the Cauchy Process
Autor: M. V. Platonova, A. K. Nikolaev
Publikováno v: Journal of Mathematical Sciences. 251:119-127
It is known that a solution to the Cauchy problem for the evolution equation, the right-hand side of which contains a convolution operator with generalized function |x|−2, admits a probabilistic representation in the form of the expectation of the

Asymptotic Behavior of the Mean Number of Particles for a Branching Random Walk on the Lattice Zd with Periodic Sources of Branching
Autor: M. V. Platonova, K. S. Ryadovkin
Publikováno v: Journal of Mathematical Sciences. 244:858-873
We consider a continuous-time branching random walk on ℤ d with birth and death of particles at a periodic set of points (sources of branching). Spectral properties of the evolution operator of the mean number of particles are studied. We derive a

A Probabilistic Approximation of the Cauchy Problem Solution for the Schrödinger Equation with a Fractional Derivative Operator
Autor: M. V. Platonova, S. V. Tsykin

We construct two types of probabilistic approximations of the Cauchy problem solution for the nonstationary Schrodinger equation with a symmetric fractional derivative of order α ∈ (1, 2) at the right-hand side. In the first case, we approximate t
