Systems with exponential eigenfunctions and exponential-input/constant-output operators [PDF]

IEEE Signal Processing Letters, 2000
Vaidyanathan (1999) and Ferreira (1999) reported on nonlinear systems with exponential eigenfunctions. In this letter, we introduce a larger class of such systems, generated from a special family of exponential-input/constant-output operators that capture exponential signals from general inputs.

Dunkl-Sobolev spaces of exponential type and applications

Journal of Function Spaces and Applications, 2011
We study the Sobolev spaces of exponential type associated with the Dunkl operators. Some properties including completeness and imbedding theorem are proved.

Telegraph model with fractional differential operators: Nonsingular kernels

Results in Physics, 2022
In this paper, a system of partial differential equations that was suggested to depict the behavior of the telegraph is considered where the time differential operators used to evaluate the rate of change is converted to nonlocal operators with the aim ...

A note on the Schrodinger operator with exponential potential

Proceedings of the Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan, 2021
Summary: The Schrödinger operator \(L=-\frac{d^2}{dx^2}+e^{2x}\) on the positive half-line with the Dirichlet boundary condition at zero is studied. A description of the domain of definition of the operator \(L\) is given. Using the connection between the modified Bessel equation and the Schrödinger equation, the distribution of the zeros of the ...

Novel Development to the Theory of Dombi Exponential Aggregation Operators in Neutrosophic Cubic Hesitant Fuzzy Sets: Applications to Solid Waste Disposal Site Selection

Complexity, 2022
The neutrosophic cubic hesitant fuzzy set can efficiently handle the complex information in a decision-making problem because it combines the advantages of the neutrosophic cubic set and the hesitant fuzzy set.

Exponential Stability of Operators and Operator Semigroups

Journal of Functional Analysis, 1995
Extending earlier results of Datko, Pazy, and Littman on \(C_0\)- semigroups, and of Przyluski and Weiss on operators, the author proves the following: Let \(T\) be a bounded linear operator on a Banach space \(X\) and let \(r(T)\) denote its spectral radius.
