On associated graded modules of maximal Cohen-Macaulay modules over hypersurface rings

Ankit Mishra, Tony J. Puthenpurakal

Let $A=Q/(f)$ where $(Q,\mathfrak{n})$ be a complete regular local ring of dimension $d+1$, $f\in {\mathfrak{n}}^i\setminus {\mathfrak{n}}^{i+1}$ for some $i\ge 2$ and $M$ an MCM $A-$m…
