Title: The deformation problem for $F$-injective singularities.
Abstract: A local ring $(R,\mathfrak{m})$ is called $F$-injective if the
Frobenius actions on all the local cohomology modules of $R$ supported at
$m$ are injective. The deformation problem asks if $R/xR$ is $F$-injective
for a regular element $x$ in $R,$ then whether $R$ is $F$-injective. I
will survey this question and prove some special cases.
