New binary and ternary LCD codes
(IEEE, 2018-05-09)
LCD codes are linear codes with important cryptographic applications. Recently, a method has been presented
to transform any linear code into an LCD code with the same parameters when it is supported on a finite field ...
Fuzzy quasi-pseudometrics on algebraic structures
(Elsevier, 2018-01)
In this work we state a number of theorems about fuzzy (quasi-)pseudometrizable algebraic structures. Our most useful results are: (1) a fuzzy semitopological group whose topology is induced by a left-invariant fuzzy ...
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 ...
The Universal Zeta Function for Curve Singularities and its Relation with Global Zeta Functions
(Springer, 2018-11-04)
The purpose of this note is to give a brief overview on zeta functions of curve singularities and to provide some evidences on how these and global zeta functions associated to singular algebraic curves over perfect fields ...
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 ...
Tutorización virtual sobre matemáticas
(UNED, 2018)
Los profesores de matemáticas, frecuentemente, encuentran problemas en la
representación de símbolos para comunicarse de manera virtual con sus estudiantes.
En este sentido y con el objetivo de facilitar la comunicación ...
Interpolation sets in spaces of continuous metric-valued functions
(Elsevier, 2018-10)
Let X and K be a Cech-complete topological group and a compact group, ˇ
respectively. We prove that if G is a non-equicontinuous subset of CHom(X; K), the set
of all continuous homomorphisms of X into K, then there is a ...
Sensitive dependence for nonautonomous discrete dynamical systems
(Elsevier, 2018-03)
Given a nonautonomous discrete dynamical system (NDS) we show that transitivity and density of periodic points do not imply sensitivity in general, i.e., in the definition of Devaney chaos there are no redundant conditions ...
Quasi-cyclic constructions of quantum codes
(Elsevier, 2018-07)
We give sufficient conditions for self-orthogonality with respect to symplec-
tic, Euclidean and Hermitian inner products of a wide family of quasi-cyclic codes of index
two. We provide lower bounds for the symplectic ...
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 ...
