Fractal and Fractional, 2021 In the three-dimensional open rectangular domain, the problem of the identification of the redefinition function for a partial differential equation with Gerasimov–Caputo-type fractional operator, degeneration, and integral form condition is considered ...

Fourier transform on the Lobachevsky plane and operational calculus [PDF]
Functional Analysis and its Applications, 54, 4 (2020), 278-286, 2020 The classical Fourier transform on the line sends the operator of multiplication by $x$ to $i\frac{d}{d\xi}$ and the operator of differentiation $\frac{d}{d x}$ to the multiplication by $-i\xi$. For the Fourier transform on the Lobachevsky plane we establish a similar correspondence for a certain family of differential operators.

Schatten class Fourier integral operators [PDF]
, 2011 Fourier integral operators with sufficiently smooth phase act on the time-frequency content of functions. However time-frequency analysis has only recently been used to analyze these operators.

On the Definition of Energy Flux in One-Dimensional Chains of Particles
Entropy, 2019 We review two well-known definitions present in the literature, which are used to define the heat or energy flux in one dimensional chains. One definition equates the energy variation per particle to a discretized flux difference, which we here show it ...

One result on boundedness of the Hilbert transform in Marcinkiewics spaces
Вестник КазНУ. Серия математика, механика, информатика, 2022 In mathematics and in signal theory, the Hilbert transform is an important linear operator that takes a real-valued function and produces another real-valued function.

Magnetic Fourier Integral Operators
, 2010 In some previous papers we have defined and studied a 'magnetic' pseudodifferential calculus as a gauge covariant generalization of the Weyl calculus when a magnetic field is present. In this paper we extend the standard Fourier Integral Operators Theory

Multigrid method for pricing European options under the CGMY process
AIMS Mathematics, 2019 We propose a fast multigrid method for solving the discrete partial integro-differential equations (PIDEs) arising from pricing European options when the underlying asset is driven by an infinite activity Lévy process.

Acta Polytechnica, 2017 We propose a new approach to the problem of finding the eigenvalues (energy levels) in the discrete spectrum of the one-dimensional Hamiltonian with an attractive Gaussian potential by using the well-known Birman-Schwinger technique. However, in place of

On rational Abel – Poisson means on a segment and approximations of Markov functions
Журнал Белорусского государственного университета: Математика, информатика, 2021 Approximations on the segment [−1, 1] of Markov functions by Abel – Poisson sums of a rational integral operator of Fourier type associated with the Chebyshev – Markov system of algebraic fractions in the case of a fixed number of geometrically different

Variations à la Fourier-Weyl-Wigner on Quantizations of the Plane and the Half-Plane
Entropy, 2018 Any quantization maps linearly function on a phase space to symmetric operators in a Hilbert space. Covariant integral quantization combines operator-valued measure with the symmetry group of the phase space.
