Pseudospectra in non-Hermitian quantum mechanics [PDF]

, 2015
We propose giving the mathematical concept of the pseudospectrum a central role in quantum mechanics with non-Hermitian operators. We relate pseudospectral properties to quasi-Hermiticity, similarity to self-adjoint operators, and basis properties of ...

Practical Theory Extension in Event-B [PDF]

, 2013
. The Rodin tool for Event-B supports formal modelling and proof using a mathematical language that is based on predicate logic and set theory. Although Rodin has in-built support for a rich set of operators and proof rules, for some application areas ...

The kernel of the edth operators on higher-genus spacelike two-surfaces [PDF]

, 2000
The dimension of the kernels of the edth and edth-prime operators on closed, orientable spacelike 2-surfaces with arbitrary genus is calculated, and some of its mathematical and physical consequences are discussed.Comment: 12 ...

K-statistical operators for set mathematical morphology

Revista Facultad de Ingeniería Universidad de Antioquia, 2013
A generalization of the basic operators in mathematical morphology is presented in this paper. The resulting generalization lead to the construction of the k-statistical operators, due to its ability to obtain geometricaly the statistical descriptors ...

Study of a Transmission Problem with Friction Law and Increasing Continuous Terms in a Thin Layer

Mathematics, 2023
The aim of this paper is to establish the asymptotic analysis of nonlinear boundary value problems. The non-stationary motion is given by the elastic constructive law. The contact is described with a version of Tresca’s law of friction.

Towards a mathematical operational semantics [PDF]

Proceedings of Twelfth Annual IEEE Symposium on Logic in Computer Science, 2002
We present a categorical theory of 'well-behaved' operational semantics which aims at complementing the established theory of domains and denotational semantics to form a coherent whole. It is shown that, if the operational rules of a programming language can be modelled as a natural transformation of a suitable general form, depending on functorial ...

Metric operators, generalized hermiticity and lattices of Hilbert lpaces [PDF]

, 2014
A quasi-Hermitian operator is an operator that is similar to its adjoint in some sense, via a metric operator, i.e., a strictly positive self-adjoint operator.

Mathematical analysis of the transmission dynamics of viral infection with effective control policies via fractional derivative

Nonlinear Engineering, 2023
It is well known that viral infections have a high impact on public health in multiple ways, including disease burden, outbreaks and pandemic, economic consequences, emergency response, strain on healthcare systems, psychological and social effects, and ...

New Inequalities Using Multiple Erdélyi–Kober Fractional Integral Operators

Fractal and Fractional
The role of fractional integral inequalities is vital in fractional calculus to develop new models and techniques in the most trending sciences. Taking motivation from this fact, we use multiple Erdélyi–Kober (M-E-K) fractional integral operators to ...
