Homomorphic encoders of profinite abelian groups I
(Elsevier, 2023-05)
Let {Gi |i ∈ N} be a family of finite Abelian groups. We say that a subgroup
G ≤
i∈N
Gi is order controllable if for every i ∈ N there is ni ∈ N such that for
each c ∈ G, there exists a ∈ G satisfying that a|[1,i] = ...
Completeness of Hutton [0,1]-quasi-uniformities induced by a crisp uniformity
(University of Sistan and Baluchestan, 2019)
In [25], Katsaras introduced a method for constructing a Hutton [0,1]-quasi-uniformity from a crisp uniformity. In thispaper we present other different methods for making this based mainly in the concept of a fuzzy uniform ...
Reliability Validation of a Low-Cost Particulate Matter IoT Sensor in Indoor and Outdoor Environments Using a Reference Sampler
(MDPI, 2019)
A suitable and quick determination of air quality allows the population to be alerted with respect to high concentrations of pollutants. Recent advances in computer science have led to the development of a high number of ...
Unsupervised classification of children’s bodies using currents
(Springer Verlag, 2018-06)
Object classification according to their shape and size is of key importance in many scientific fields. This work focuses on the case where the size and shape of an object is characterized by a current. A current is a ...
Discrete maximal regularity for Volterra equations and nonlocal time-stepping schemes
(American Institute of Mathematical Sciences, 2020)
In this paper we investigate conditions for maximal regularity of Volterra equations defined on the Lebesgue space of sequences ‘p(Z) by using Bl¨unck’s theorem on the
equivalence between operator-valued ‘p-multipliers ...
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 ...
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 ...
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 ...
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 ...
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 ...
