**Title:** Cowsik-Nori theorem on curves

**Speaker: ** Manoj Keshari, IIT Bombay

**Abstract:** We will see a proof of the Cowsik-Nori theorem, which states that if $k$ is a field of positive characteristic, and $I$ is a prime ideal of
$k[X_1,\ldots,X_n]$ of height $n-1$, then up to radical, $I$ is generated by $n-1$ elements.
