Use the notation above: let $d\geq1$, let $p>2$ be prime, define … and let $(A,\mathfrak m,k)$ be a $d$-dimensional unmixed local ring with $k=\overline{\mathbb F_p}$. Higher-dimen…

Let $d\geq1$ be an integer and let $p>2$ be prime. Define … Let $(A,\mathfrak m,k)$ be a $d$-dimensional unmixed local ring with $k=\overline{\mathbb F_p}$. Han–Monsky lower-bound…

Let $p$ be an odd prime and let … which is a singular ring of characteristic $p$ and dimension $d-1$. For a Noetherian local ring $(R,\mathfrak{m})$ of characteristic $p$, write…

Let $d\geq 2$. Set … where … Let $(R,\mathfrak{m},k)$ be an unmixed non-regular local ring of characteristic $p$ and dimension $d$. Here, unmixed means that…

Let $(R,\mathfrak{m},K)$ be a local ring. Let $I\subseteq R$ be an ideal generated by a part of a system of parameters $(f_1,\ldots,f_\ell)$, and set $\overline{R}=R/I$. Let $J$ be…
