Low Regularity Exponential-Type Integrators for Semilinear Schrödinger Equations [PDF]

Foundations of Computational Mathematics, 2016
We introduce low regularity exponential-type integrators for nonlinear Schrödinger equations for which first-order convergence only requires the boundedness of one additional derivative of the solution.

Quintessence arising from exponential potentials [PDF]

, 1999
We demonstrate how exponential potentials that could arise in the early Universe as a result of Kaluza-Klein type compactifications of string theory, can lead to cosmological solutions which correspond to the currently observed accelerating Universe. The

Trapezium-Type Inequalities for k-Fractional Integral via New Exponential-Type Convexity and Their Applications

Journal of Mathematics, 2020
In this paper, the authors investigated the concept of s,m-exponential-type convex functions and their algebraic properties. New generalizations of Hermite–Hadamard-type inequality for the s,m-exponential-type convex function ψ and for the products of ...

Convergence estimates of a family of approximation operators of exponential type

, 2020
The main object of this article is to consider a family of approximation operators of exponential type, which has presumably not been studied earlier due mainly to their seemingly complicated behavior.

Exponential dichotomies of evolution operators in Banach spaces

, 2014
This paper considers three dichotomy concepts (exponential dichotomy, uniform exponential dichotomy and strong exponential dichotomy) in the general context of non-invertible evolution operators in Banach spaces.

Datko-type theorems concerning asymptotic behaviour of exponential type in mean [PDF]

Opuscula Mathematica
In this paper, we study the concept of exponential (in)stability in mean for stochastic skew-evolution semiflows, in which the exponential (in)stability in the classical sense is replaced by an average with respect to a probability measure.

Moment-Type Estimation in the Exponential Family [PDF]

Communications in Statistics - Simulation and Computation, 1974
Some aspects of the Pearson-Fisher controversy concerning the method of moments and the method of maximum likelihood are reviewed. In the multiparameter exponential family, a modification of the method of moments which requires the estimators to be functions of the minimal sufficient statistic is discussed It is shown that these modified estimators are

Difference in dwarf galaxy surface brightness profiles as a function of environment

, 2018
We investigate surface brightness profiles (SBPs) of dwarf galaxies in field, group, and cluster environments. With deep $BVI$ images from the Korea Microlensing Telescope Network Supernova Program, SBPs of 38 dwarfs in the NGC 2784 group are fitted by a

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.
