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 ...
Maximal lp-regularity for discrete time Volterra equations with delay
(Taylor & Francis, 2019-07-08)
In this paper, we investigate the existence and uniqueness of solutions belonging to the vector-valued space ℓp(Z,X) by using Blunck's theorem on the equivalence between operator-valued ℓp-multipliers and the notion of ...
Method to determine which quantum operations can be realized with linear optics with a constructive implementation recipe
(American Physical Society, 2019-08-02)
The evolution of quantum light through linear optical devices can be described by the scattering matrix S of the system. For linear optical systems with m possible modes, the evolution of n input photons is given by a ...
Transitivity in Fuzzy Hyperspaces
(MDPI, 2020)
Given a metric space (X, d), we deal with a classical problem in the theory of hyperspaces:
how some important dynamical properties (namely, weakly mixing, transitivity and point-transitivity)
between a discrete dynamical ...

Global and Local Three-dimensional Studies of The Residual Vector Field from 2MASS and Hipparcos-2 Catalog
(Astronomical Society of the PacificIOP, 2019-04)
The Gaia mission will provide a six-parameter solution for millions of stars, including a tridimensional map of our Galaxy. The estimation of distances has been made for the Tycho-Gaia Astrometric Solution (TGAS), while ...
Dynamical Analysis to Explain the NumericalAnomalies in the Family of Ermakov-KalitkinType Methods
(Vilnius Gediminas Technical University (VGTU) Press, 2019)
In this paper, we study the dynamics of an iterative method based onthe Ermakov-Kalitkin class of iterative schemes for solving nonlinear equations. Asit was proven in ”A new family of iterative methods widening areas of ...
Occultation of Planets by the Moon in European Narrative Medieval Sources
(Sage, 2019-05)
Existing research dealing with astronomical observations from medieval Europe have
extensively covered topics such as solar and lunar eclipses and sightings of comets and meteors, but no
compilation of occultations of ...
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 ...
Challenges Regarding Scientific Transcription in Virtual Office Hours
(MDPI, 2021-03-24)
Mathematics teachers face great difficulties during virtual communication with their
students, mainly because scientific and technical subjects use a great many mathematical symbols,
abstract objects and a wide variety ...
