Unipotent Algebraic Groups

Rothschild, Seth.


  • Abstract: Let Ga be the additive algebraic group over an algebraically closed field k of odd characteristic. This thesis considers group extensions H of Ga by Ga. By [Ros56], every unipotent group has a closed subgroup isomorphic to Ga and a quotient which is isomorphic to Ga. By studying extensions of Ga by Ga, we study every connected two dimensional unipotent group. In Chapter 4, we provide the... read more
