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 ...
Hölder regularity for the Moore-Gibson-Thompson equation with infinite delay
(American Institute of Mathematical Sciences (AIMS), 2018-01)
We characterize the well-posedness of a third order in time equation with infinite delay in Holder spaces, solely in terms of spectral properties concerning the data of the problem. Our analysis includes the case of the ...
Complete invariant fuzzy metrics on groups
(Elsevier, 2018-01-01)
We
study some questions related to complete fuzzy metric topological groups (in the sense of Kramosil and Michael). Invariant
fuzzy metrics are characterized and we prove that if (G, M, ∗) is a fuzzy metric group such ...
Classical and Quantum Evaluation Codesat the Trace Roots
(IEEE, 2019-04)
We introduce a new class of evaluation linear codes by evaluating polynomials at the roots of a suitable trace function. We give conditions for self-orthogonality of these codes and their subfield-subcodes with respect to ...
Convergence analysis of high-order commutator-free quasi-Magnus exponential integrators for nonautonomous linear evolution equations of parabolic type
(Oxford University Press, 2018-04)
The main objective of this work is to provide a stability and error analysis of high-order commutator-free quasi-Magnus (CFQM) exponential integrators. These time integration methods for nonautonomous linear evolution ...
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 ...
[S]-linear and convex structures in function families
(Elsevier, 2019)
In this paper, the notion of [S]-lineability (originally coined
by Vladimir I. Gurariy) is introduced and developed in a general abstract
setting. This new notion is, then, applied to specific situations, as for
instance, ...
Fast Algorithms for the Computation of the Minimum Distance of a Random Linear Code
(Association for Computing Machinery (ACM), 2019-06)
The minimum distance of an error-correcting code is an important concept in information theory. Hence, computing the minimum distance of a code with a minimum computational cost is crucial to many problems in this area. ...
A general formula for the Magnus expansion in terms of iterated integrals of right-nested commutators
(IOP, 2018-03)
We present a general expression for any term of the Magnus series as an iterated integral of a linear combination of independent right-nested commutators with given coefficients. The relation with the Malvenuto–Reutenauer ...
