Abstract

In the paper, we study the nonlocal problem for a fractional partial differential equation with the Hilfer derivative. The non-local boundary value problem, \(D^{\alpha,\beta}u(t)+Au(t)=f(t)\) (\(0<\alpha<1\), \(0\leq\beta\leq 1\) and \(0<t\leq T\)), \(I^{\delta}u(t)=\gamma I^{\delta}u(+0)+\varphi\) (\(\gamma\) is a constant), in an arbitrary separable Hilbert space H with the strongly positive self-adjoint operator \(A\), is considered. In addition to the forward problem, the article also explores the inverse problem of determining the right-hand side of the equation. Existence and uniqueness theorems are proved to solve the forward and inverse problems.

论具有希尔费分式衍生物的方程的非局部问题

摘要本文研究了具有希尔费导数的分数偏微分方程的非局部问题。非局部边界值问题，(D^{\alpha,\beta}u(t)+Au(t)=f(t)\) (（0<\alpha<1\), （0\leq\beta\leq 1\) and\(0<；tleq T\)), \(I^{\delta}u(t)=\gamma I^{\delta}u(+0)+\varphi\) （（\(\gamma\)是一个常数），在一个任意可分离的希尔伯特空间H中与强正自相加算子\(A\)一起被考虑。除了正向问题，文章还探讨了确定方程右边的反向问题。证明了求解正向和反向问题的存在性和唯一性定理。
