TITLE: A toy example of a tensor triangulated category?
QUESTION [13 upvotes]: I've been reading Paul Balmer's paper about constructing a "spectrum of prime ideals" on an (essentially small) tensor triangulated category in order to then classify thick subcategories. This is all done to generalize work done in various fields throughout mathematics (e.g. Devinatz, Hopkins, and Smith's work in stable homotopy theory, and Pevtsova and Friedlander's work in finite group schemes). The classic examples of tensor triangulated categories that Balmer talks about are the category of spectra, the category of $G$-modules for some finite group scheme $G$, or the perfect derived category associated to a (topologically Noetherian) scheme (this is related to Thomason's work reconstructing a scheme from the aforementioned category).
But I can't, for the life of me, think of more examples of tensor triangulated categories! (I'm new at all of this...) Can anyone give me a "toy" example of a tensor-triangulated category that is not an example of any of the ones I just listed? By "toy" example I mean that it should be relatively simple with an easy to understand structure. The purpose will be so that I can do Balmer's construction on the toy category to get a better understanding of what's going on.

REPLY [4 votes]: Take a finite dimensional Hopf algebra $H$, the category of $H$-modules is Frobenius (projectives=injectives and there is enough of both); e.g. take $H$ to be the group algebra of a finite group.   So the stable category is triangulated (see Happel's book). In these examples, the usual tensor product of $H$-modules is well defined in the stable category.
This is explained in Khovanov's paper here.    and developed further by You Qi. I recently upload a preprint considering co-Frobenius Hopf algebras (i.e. not necesarily finite dimensional Hopf algebras admitting a (left or right) integral $\Lambda\in H^*$, https://arxiv.org/abs/1904.10430)
The category of comodules over a co-Frobenius Hopf algebra is Frobenius, the stable category is triangulated and the standard tensor product of comodules is well defined in the stable category.
