Condition pseudospectrum in non-Archimedean Banach spaces [PDF]

Journal of Mahani Mathematical Research
In this article, we introduce and study the condition pseudospectrum of bounded linear operator pencils on non-Archimedean Banach spaces. We obtain a characterization of the condition pseudospectrum of bounded linear operator pencils on non-Archimedean ...

The constrained modified KP hierarchy and the generalized Miura transformations

, 1997
In this letter, we consider the second Hamiltonian structure of the constrained modified KP hierarchy. After mapping the Lax operator to a pure differential operator the second structure becomes the sum of the second and the third Gelfand-Dickey brackets

Differential sandwich theorems of p−valent analytic functions involving a linear operator

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
In this paper we derive some subordination and superordination results for certain p-valent analytic functions in the open unit disc, which are acted upon by a class of a linear operator.

An "Accidental" Symmetry Operator for the Dirac Equation in the Coulomb Potential

, 2005
On the basis of the generalization of the theorem about K-odd operators (K is the Dirac's operator), certain linear combination is constructed, which appears to commute with the Dirac Hamiltonian for Coulomb field.

Differential sandwich theorems for higher-order derivatives of p-valent functions involving a generalized differential operator

Le Matematiche, 2014
In the present article, we obtain some applications of first order differential subordination, superordination and sandwich results for higher-order derivatives of p-valent functions involving a generalized differential operator.

Operator synthesis II. Individual synthesis and linear operator equations

, 2004
The second part of our work on operator synthesis deals with individual operator synthesis of elements in some tensor products, in particular in Varopoulos algebras, and its connection with linear operator equations.

High order Fuchsian equations for the square lattice Ising model: $\chi^{(6)}$

, 2009
This paper deals with $\tilde{\chi}^{(6)}$, the six-particle contribution to the magnetic susceptibility of the square lattice Ising model. We have generated, modulo a prime, series coefficients for $\tilde{\chi}^{(6)}$.

Fuzzy Subordination Results for Meromorphic Functions Connected with a Linear Operator

Fractal and Fractional
The concept of subordination is expanded in this study from the fuzzy sets theory to the geometry theory of analytic functions with a single complex variable.

Koopman operator-based model reduction for switched-system control of PDEs

, 2019
We present a new framework for optimal and feedback control of PDEs using Koopman operator-based reduced order models (K-ROMs). The Koopman operator is a linear but infinite-dimensional operator which describes the dynamics of observables.

Adaptive Bayesian and frequentist data processing for quantum tomography

, 2009
The outcome statistics of an informationally complete quantum measurement for a system in a given state can be used to evaluate the ensemble expectation of any linear operator in the same state, by averaging a function of the outcomes that depends on the
