Asymptotic depth of Ext modules over complete intersection rings

Let $(A,\mathfrak{m})$ be a local complete intersection ring and let $I$ be an ideal in $A$. Let $M,N$ be finitely generated $A$-modules. Then for $l = 0,1$,thevalues$depth \ Ext^{2i+l}_A(M, N/I^nN)$becomeindependentof$i, n$for$i,n \gg 0$\mathrm{.}Wealsoshowthatif$\mathfrak{p}$isaprimeidealin$A$thenthe$j^{th}$Bassnumbers$\mu_j\big(\mathfrak{p},
