Sturm-Liouville operator with general boundary conditions

open access: yesElectronic Journal of Differential Equations, 2005
We classify the general linear boundary conditions involving $u''$, $u'$ and $u$ on the boundary ${a,b}$ so that a Sturm-Liouville operator on $[a,b]$ has a unique self-adjoint extension on a suitable Hilbert space.

Lyapunov functions for linear nonautonomous dynamical equations on time scales

open access: yesAdvances in Difference Equations, 2006
The existence of a Lyapunov function is established following a method of Yoshizawa for the uniform exponential asymptotic stability of the zero solution of a nonautonomous linear dynamical equation on a time scale with uniformly bounded graininess.

A model of distributed object­based stochastic hybrid systems

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
This article offers a mathematical model for distributed object­oriented stochastic hybrid systems (DOBSHS). DOBSHS are composite objects communicating with other objects through the exchange of messages through an asynchronous medium such as a network ...

Radial minimizers of a Ginzburg-Landau functional

open access: yesElectronic Journal of Differential Equations, 1999
We consider the functional $$ E_varepsilon(u,G) =frac 1pint_G|abla u|^p +frac{1}{4varepsilon^p}int_G(1-|u|^2)^2 $$ with $p>2$ and $d>0$, on the class of functions $W={u(x)=f(r)e^{idheta} in W^{1,p}(B,C); f(1)=1,f(r)geq 0}$.

Harmonic solutions to a class of differential-algebraic equations with separated variables

open access: yesElectronic Journal of Differential Equations, 2012
We study the properties of periodic solutions of a class of periodically perturbed Differential-Algebraic Equations with separated variables. Under suitable hypotheses, these equations are equivalent to separated variables ODEs on a manifold.

Solution of Integral Equation using Second and Third Order B-Spline Wavelets [PDF]

open access: yes
It was proven that semi-orthogonal wavelets approximate the solution of integral equation very finely over the orthogonal wavelets Here we used the compactly supported semi-orthogonal B-spline wavelets generated in our paper Compactly Supported B ...

Two Sharp Inequalities for Power Mean, Geometric Mean, and Harmonic Mean

open access: yesJournal of Inequalities and Applications, 2009
For p∈R, the power mean of order p of two positive numbers a and b is defined by Mp(a,b)=((ap+bp)/2)1/p,p≠0,  and  Mp(a,b)=ab,   p=0.
