Tambara structure on Grothendieck rings of some Galois ring extension

The thesis studies existence of Tambara structure on Grothendieck rings of C_2-Galois extension of rings. Tambara structure is given by two rings, three functions between them and group action on one of those rings all satisfying some conditions. In following work we construct these functions and a group action for Grothendieck rings of C_2-Galois extension of rings and verify aforementioned conditions.
