Operational calculus for holonomic distributions in the framework of D-module theory

Let $f$ be a real polynomial of $x = (x_1,\dots,x_n)$ and $φ$ be a locally integrable function of $x$ which satisfies a holonomic system of linear differential equations. We study the distribution $f_+^λφ$ with a meromorphic parameter $λ$, especially its Laurent expansion and integration, from an algorithmic viewpoint in the framework of $D$-module theory.
