Unipotent Group Actions on Del Pezzo Cones
Takashi Kishimoto, Yuri Prokhorov, Mikhail Zaidenberg
In a previous paper we established that for any del Pezzo surface Y of degree at least 4, the affine cone X over Y embedded via a pluri-anticanonical linear system admits an effect…
Log-uniruled affine varieties without cylinder-like open subsets
Adrien Dubouloz, Takashi Kishimoto
A classical result of Miyanishi-Sugie and Keel-McKernan asserts that for smooth affine surfaces, affine-uniruledness is equivalent to affine-ruledness, both properties being in fac…
Affine cones over Fano threefolds and additive group actions
Takashi Kishimoto, Yuri Prokhorov, Mikhail Zaidenberg
We address the following question: When an affine cone over a smooth Fano threefold admits an effective action of the additive group? In this paper we deal with Fano threefolds of…
