Rigidity And Unirational Groups

Zev Rosengarten

We prove a rigidity theorem for morphisms from products of open subschemes of the projective line into solvable groups not containing a copy of $\Ga$ (for example, wound unipotent…

Permawound Unipotent Groups

Zev Rosengarten

We introduce the class of permawound unipotent groups, and show that they simultaneously satisfy certain "ubiquity" and "rigidity" properties that in combination render them very u…
