Attached primes of the top local cohomology modules with respect to an ideal

Let $(R,\mathfrak{m})$ be a Noetherian local ring and let $\mathfrak{a}$ be an ideal of R. Let M be an R-module of dimension n. In this paper we study the attached primes of the top local cohomology module ${\text{H}}_\mathfrak{a}^n (M).$
