Bruhat-Tits group schemes over higher dimensional base-II
Vikraman Balaji, Yashonidhi Pandey
We prove that split reductive BT group schemes over a higher dimensional base are {\em affine}. Our method also gives a new construction of higher BT-group schemes more general tha…

On Bruhat-Tits theory over a higher dimensional base
Vikraman Balaji, Yashonidhi Pandey
Let be a perfect field. Assume that the characteristic of satisfies certain tameness assumptions \eqref{tameness}. Let $\mathcal O_{_n} := k\llbracket z_{_1}, \ldots, z_{_n…
