具有一般边界条件的Nabla分式边值问题

On a Nabla Fractional Boundary Value Problem with General Boundary Conditions

Jagan Mohan Jonnalagadda

摘要:

在这篇文章中,我们考虑了一类具有一般边界条件的nabla分数阶边值问题。Brackins \& Peterson \cite{Br}给出了相应格林函数的显式表达式。在这里,我们表明,这个格林函数是非负的,并获得其最大值的上界。由于格林函数的表达式是复杂的,其性质的推导可能并不简单。为此,我们使用分数阶nabla泰勒单项式的一些性质。利用格林函数,我们将开发一个Lyapunov型不等式的nabla分数边值问题。

英文摘要:

In this article, we consider a nabla fractional boundary value problem with general boundary conditions. Brackins \& Peterson \cite{Br} gave an explicit expression for the corresponding Green's function. Here, we show that this Green's function is nonnegative and obtain an upper bound for its maximum value. Since the expression for the Green's function is complicated, derivation of its properties may not be straightforward. For this purpose, we use a few properties of fractional nabla Taylor monomials. Using the Green's function, we will then develop a Lyapunov-type inequality for the nabla fractional boundary value problem.
