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…

Locally finite sets of derivations

Michael Chitayat, Daniel Daigle, Andriy Regeta

Given an algebra B over a field k, we study conditions under which a Lie subalgebra of Der(B) is locally finite as a set of derivations. As an application of our results, we show t…

The Fundamental Group of a Compact Riemann Surface via Branched Covers

Meirav Amram, Michael Chitayat, Yaacov Kopeliovich

Let $X$ be a compact Riemann surface of genus $g$ and let $x \in X$ . We derive the classical presentation of $I ¨ _{1} (X, x)$ (i.e the one given by $2 g$ generators $a_1,b_1, \dots, a_g,…

The Rigid Pham-Brieskorn Threefolds

Michael Chitayat, Adrien Dubouloz

We show that a $3$ -dimensional Pham-Brieskorn hypersurface ${X_{0}^{a_{0}} + X_{1}^{a_{1}} + X_{2}^{a_{2}} + X_{3}^{a_{3}} = 0}$ in $A^{4}$ such that $min {a_{0}, a_{1}, a_{2}, a_{3}} \geq 2$ a…
