The minimizer for the second order differential problem with the integral condition

open access: yesLietuvos Matematikos Rinkinys, 2019
In this paper, we investigate the best fit solution for the second order differential problem with one initial and other integral conditions. We obtain the representation of that minimizer and present an example.paration.

GENERALIZED CONDITIONAL INTEGRAL TRANSFORMS, CONDITIONAL CONVOLUTIONS AND FIRST VARIATIONS [PDF]

open access: yesKorean Journal of Mathematics, 2012
Summary: We study various relationships that exist among generalized conditional integral transform, generalized conditional convolution and generalized first variation for a class of functionals defined on \(K[0, T]\), the space of complex-valued continuous functions on \([0, T]\) which vanish at zero.

An Unusual Moving Boundary Condition Arising in Anomalous Diffusion Problems [PDF]

open access: yes, 1995
In the context of analyzing a new model for nonlinear diffusion in polymers, an unusual condition appears at the moving interface between the glassy and rubbery phases of the polymer.

On the double Lusin condition and convergence theorem for Kurzweil-Henstock type integrals [PDF]

open access: yesMathematica Bohemica, 2016
Equiintegrability in a compact interval $E$ may be defined as a uniform integrability property that involves both the integrand $f_n$ and the corresponding primitive $F_n$.

Negligible Variation and the Change of Variables Theorem

open access: yes, 2012
In this note we prove a necessary and sufficient condition for the change of variables formula for the HK integral, with implications for the change of variables formula for the Lebesgue integral.

On the Coherent State Path Integral for Linear Systems [PDF]

open access: yes, 2005
We present a computation of the coherent state path integral for a generic linear system using ``functional methods'' (as opposed to discrete time approaches).

Parts formulas involving conditional Feynman integrals [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2002
In this paper we first obtain a basic formula for the conditional analytic Feynman integral of the first variation of a functional on Wiener space. We then apply this basic result to obtain several integration by parts formulas for conditional analytic Feynman integrals and conditional Fourier-Feynman transforms.

Uniqueness of Gibbs Measure for Models With Uncountable Set of Spin Values on a Cayley Tree

open access: yes, 2012
We consider models with nearest-neighbor interactions and with the set $[0,1]$ of spin values, on a Cayley tree of order $k\geq 1$. It is known that the "splitting Gibbs measures" of the model can be described by solutions of a nonlinear integral ...

On solvability of nonlinear boundary value problems with integral condition for the system of hyperbolic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
For system of hyperbolic equations of second order a nonlinear boundary value problem with integral condition is considered. By introducing new unknown functions the investigated problem is reduced to an equivalent problem involving one-parametered ...

QUANTUM LIE SYSTEMS AND INTEGRABILITY CONDITIONS [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2009
The theory of Lie systems has recently been applied to Quantum Mechanics and additionally some integrability conditions for Lie systems of differential equations have also recently been analyzed from a geometric perspective. In this paper we use both developments to obtain a geometric theory of integrability in Quantum Mechanics and we use it to ...
