Chow-Witt Rings of Classifying Spaces of Products of Multiplicative and Cyclic Groups
Abstract
We compute the total Chow-Witt rings of the classifying space Bμn of the roots of unity, as well as the products BGm x Bμn and Bμm x Bμn for all m,n greater than or equal to 1 based on the strategy by di Lorenzo and Mantovani (2023) for Bμn with n even. Moreover we compute the total Ij-cohomology and Chow-Witt rings of Pq x Pr for all q,r greater than or equal to 1 and of BGm x BGm.
