Abstract: Let $ \mathcal{F} = \{ F_n \}$ be a multiplicative filtration of a local ring such that the Rees algebra $ \mathrm{R}(\mathcal{F})$ is Noetherian. We recall Burch's inequality for $ \mathcal{F}$ and give an upper bound of the a-invariant of the associated graded ring $ \mathrm{a}(\mathrm{G}(\mathcal{F}))$ using a reduction system of $ \mathcal{F}$. Applying those results, we study the symbolic Rees algebra of certain ideals of dimension $ 2$.
