Borel subgroups of the automorphism group of an affine variety

Michael Chitayat, Daniel Daigle, Andriy Regeta

We study Borel subgroups of the automorphism group of an affine variety X and their associated Lie algebras. We prove a bijective correspondence between the set of Borel subgroups…

The Isomorphism Classes of the Surfaces $x_{1}^{a_{1}} + x_{2}^{a_{2}} + x_{3}^{a_{3}} + 1 = 0$

Michael Chitayat, Buddhadev Hajra

Let $f = x_{1}^{a_{1}} + x_{2}^{a_{2}} + x_{3}^{a_{3}} + 1 \in C [x_{1}, x_{2}, x_{3}]$ and let $g = y_{1}^{b_{1}} + y_{2}^{b_{2}} + y_{3}^{b_{3}} + 1 \in C [y_{1}, y_{2}, y_{3}]$ where $a_1,a_2,a_3,b_1,b…
