Functions and integrals [PDF]

open access: yesTransactions of the American Mathematical Society, 1972
In §2 a mapping of nonnegative functions is defined to be an integral if it has the following properties: I ( f ) ⩾ 0 , I ( f ) > ∞ I(f) \geqslant 0,I(f) > \infty for some f f , if f ⩽ g f ...

Integrals involvingE-functions [PDF]

open access: yesMathematische Zeitschrift, 1958
1. Introductory. The following two integrals will be established in § 2.If m is a positive integer, if p ≧ q + 1 and if R(ar+kt) > 0 (r = 1, 2,…, p, t = 1, 2,…, m),where co is 1 or e±in according as m is even or odd, the dash denotes that the factor sin (k,–k,)π does not appear and the asterisk that the parameter kt–kt + 1 is omitted.

New Covariant Density Functionals of Nuclear Matter for Compact Star Simulations

open access: yesThe Astrophysical Journal, 2023
We generate three families of extended covariant density functionals of nuclear matter that have varying slope of symmetry energy and skewness at nuclear saturation density, but otherwise share the same basic parameters (symmetry energy, compressibility,

Minimization of nonsmooth integral functionals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
In this paper we examine optimization problems involving multidimensional nonsmooth integral functionals defined on Sobolev spaces. We obtain necessary and sufficient conditions for optimality in convex, finite dimensional problems using techniques from ...

Weighted Integral Inequalities for Harmonic Convex Functions in Connection with Fejér’s Result

open access: yesAxioms, 2022
In this study, on the subject of harmonic convex functions, we introduce some new functionals linked with weighted integral inequalities for harmonic convex functions. In addition, certain new inequalities of the Fejér type are discovered.

Conditional generalized analytic Feynman integrals and a generalized integral equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We use a generalized Brownian motion process to define a generalized Feynman integral and a conditional generalized Feynman integral. We then establish the existence of these integrals for various functionals.

On integral inequalities related to the weighted and the extended Chebyshev functionals involving different fractional operators

open access: yesJournal of Inequalities and Applications, 2020
The role of fractional integral operators can be found as one of the best ways to generalize classical inequalities. In this paper, we use different fractional integral operators to produce some inequalities for the weighted and the extended Chebyshev ...

Stability of port-Hamiltonian systems with mixed time delays subject to input saturation

open access: yesNonlinear Analysis, 2023
In this paper, we investigate the stability of port-Hamiltonian systems with mixed time-varying delays as well as input saturation. Three types of time delays, including state delay, input delay, and output delay, are all assumed to be bounded.
