Well-posedness for degenerate third order equations with delay and applications to inverse problems
(SpringerThe Hebrew University Magnes Press, 2018-10)
In this paper, we study well-posedness for the following third-order in time equation with delay
(0.1)α(Mu′)′′(t)+(Nu′)′(t)=βAu(t)+γBu′(t)+Gu′t+Fut+f(t),t∈[0,2π]
where α, β, γ are real numbers, A and B are linear operators ...
Computing the matrix sine and cosine simultaneously with a reduced number of products
(Elsevier, 2021-05)
A new procedure is presented for computing the matrix cosine and sine simultaneously by means of Taylor polynomial approximations. These are factorized so as to reduce the number of matrix products involved. Two versions ...
QOptCraft: A Python package for the design and study of linear optical quantum systems
(Elsevier, 2022-08-29)
The manipulation of the quantum states of light in linear optical systems has multiple applications in quantum optics and quantum computation. The package QOptCraft gives a collection of methods to solve some of the most ...
Exponential Perturbative Expansions and Coordinate Transformations
(MDPI, 2020)
We propose a unified approach for different exponential perturbation techniques used in
the treatment of time-dependent quantum mechanical problems, namely the Magnus expansion,
the Floquet–Magnus expansion for periodic ...
Pointwise convergence topology and function spaces in fuzzy analysis
(University of Sistan and Baluchestan, 2018-03)
We study the space of all continuous fuzzy-valued functions from a space $X$ into the space of fuzzy numbers $(\mathbb{E}\sp{1},d\sb{\infty})$ endowed with the pointwise convergence topology. Our results generalize the ...
The Lie-group method based on radial basis functions for solving nonlinear high dimensional generalized Benjamin–Bona–Mahony–Burgers equation in arbitrary domains
(Elsevier, 2018-03-15)
The aim of this paper is to introduce a new numerical method for solving the nonlinear generalized Benjamin–Bona–Mahony–Burgers (GBBMB) equation. This method is combination of group preserving scheme (GPS) with radial basis ...
A note on the Baker–Campbell–Hausdorff series in terms of right-nested commutators
(Springer, 2021-01-27)
We get compact expressions for the Baker–Campbell–Hausdorff
series Z = log(eX eY ) in terms of right-nested commutators. The reduction in the number of terms originates from two facts: (i) we use as a
starting point an ...
Generalized Weierstrass semigroups and their Poincaré series.
(Elsevier, 2019-07)
We investigate the structure of the generalized Weierstrass semigroups at several points on a curve defined over a finite field. We present a description of these semigroups that enables us to associate them with combinatorial ...
On using Reproducing Kernel Hilbert Spaces for the analysis of Replicated Spatial Point Processes
(Elsevier, 2023)
This paper focuses on the use of the theory of Reproducing
Kernel Hilbert Spaces in the statistical analysis of replicated point
processes. We show that spatial point processes can be observed
as random variables in a ...
Multiple photon effective Hamiltonians in linear quantum optical networks
(Elsevier, 2019)
We give an alternative derivation for the explicit formula of the effective Hamiltonian describing the evolution
of the quantum state of any number of photons entering a linear optics multiport. The description is based ...
