Query: "Frobenius twists" in the representation theory of the symmetric group   For the general linear group $GL_n(k)$ over an algebraically closed field $k$
of characteristic $p$, there are two types of "twisting" operations that arise
naturally on partitions. These are of the form $\lambda \rightarrow p\lambda$
and $\lambda \rightarrow \lambda + p^r\tau$ The first comes from the Frobenius
twist, and the second arises in various tensor product situations, often from
tensoring with the Steinberg module. This paper surveys and adds to an
intriguing series of seemingly unrelated symmetric group results where this
partition combinatorics arises, but with no structural explanation for it. This
includes cohomology of simple, Specht and Young modules, support varieties for
Specht modules, homomorphisms between Specht modules, the Mullineux map,
$p$-Kostka numbers and tensor products of Young modules.
