The double integrals of 2- refined neutrosophic functions and its applications [PDF]
Neutrosophic Sets and SystemsThe importance of this paper comes from the fact that it presented a study of the double integrals of 2- refined neutrosophic functions and its applications, where we presented several theories for the concept of the double integrals of 2- refined ...

Weak uniqueness and density estimates for sdes with coefficients depending on some path-functionals [PDF]
, 2017 In this paper, we develop a general methodology to prove weak uniqueness for stochastic differential equations with coefficients depending on some path-functionals of the process.

Banach limits: extreme properties, invariance and the Fubini theorem
St. Petersburg Mathematical Journal, 2022 A Banach limit on the space of all bounded real sequences is a positive normalized linear functional that is invariant with respect to the shift. The paper studies such properties of Banach limits as multiplicativity and the validity of Fubini’s theorem.

The equality of mixed partial derivatives under weak differentiability conditions
, 2014 We review and develop two little known results on the equality of mixed partial derivatives which can be considered the best results so far available in their respective domains.

Dispersive Bounds for the three-dimensional Schrodinger equation with almost critical potentials
, 2004 We prove a dispersive estimate for the time-independent Schrodinger operator H = -\Delta + V in three dimensions. The potential V(x) is assumed to lie in the intersection L^p(R^3) \cap L^q(R^3), p < 3/2 < q, and also to satisfy a generic zero-energy ...

Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

Hardy-Copson Type Inequalities on Time Scales for the Functions of “n” Independent Variables
International Journal of Analysis and Applications, 2019 The paper consists of some extensions in Hardy and Copson type inequalities on time scales. The main results are proved by using induction principle, Rules to find derivatives for composition of two functions, H¨older’s inequality and Fubini’s theorem in

On the Mean‐Field Limit of Consensus‐Based Methods
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Consensus‐based optimization (CBO) employs a swarm of particles evolving as a system of stochastic differential equations (SDEs). Recently, it has been adapted to yield a derivative free sampling method referred to as consensus‐based sampling (CBS). In this paper, we investigate the “mean‐field limit” of a class of consensus methods, including

Naval Research Logistics (NRL), EarlyView.ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Calder\'on-Zygmund operators in the Bessel setting
, 2010 We study several fundamental operators in harmonic analysis related to Bessel operators, including maximal operators related to heat and Poisson semigroups, Littlewood-Paley-Stein square functions, multipliers of Laplace transform type and Riesz ...
