Necessary optimality conditions for fractional action-like problems with intrinsic and observer times

open access: yes, 2008
We prove higher-order Euler-Lagrange and DuBois-Reymond stationary conditions to fractional action-like variational problems.

Fractional-order boundary value problem with Sturm-Liouville boundary conditions

open access: yesElectronic Journal of Differential Equations, 2015
Using the new conformable fractional derivative, which differs from the Riemann-Liouville and Caputo fractional derivatives, we reformulate the second-order conjugate boundary value problem in this new setting.

A Liouville theorem for elliptic systems with degenerate ergodic coefficients

open access: yes, 2018
We study the behavior of second-order degenerate elliptic systems in divergence form with random coefficients which are stationary and ergodic. Assuming moment bounds like Chiarini and Deuschel (2014) on the coefficient field a and its inverse, we prove ...

On the analytic form of the discrete Kramer sampling theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
The classical Kramer sampling theorem is, in the subject of self-adjoint boundary value problems, one of the richest sources to obtain sampling expansions. It has become very fruitful in connection with discrete Sturm-Liouville problems.
