A higher Verlinde category is the finite
symmetric tensor category in characteristic
obtained as the abelian envelope
of the quotient of the tilting-module category
of
by the tensor ideal generated by the Steinberg module
of highest weight
. Here
is algebraically closed
and
.
At level one it is the semisimplification of the representation category
of the cyclic group of order
, obtained by removing morphisms
whose trace pairings all vanish. Its simple objects are
represented by the Jordan blocks of sizes 1 through
.
Thus
is equivalent to finite-dimensional vector spaces,
while
is equivalent to finite-dimensional super vector spaces.
Higher levels are not semisimple. They are proposed as targets for fiber
functors from finite symmetric
tensor categories (Benson et al. 2023).
