ABSTRACT The Ogasawara Islands, representing an oceanic island ecosystem in Japan, have a notably high rate of endemic species akin to other oceanic islands globally. Pittosporum parvifolium is a critically endangered shrub with only four remaining i

Crepidiastrum grandicollum is a critically endangered insular endemic herb found only on two oceanic islands of the Bonin Islands in Japan, namely Chichijima Island and Anijima Island. It is explicitly threatened by herbivory pressure from introduced

Automorphism groups of vector groups over a field of positive characteristic

Autor: Takefumi Tanaka, Hitoshi Kaneta

Publikováno v: Hiroshima Math. J. 38, no. 3 (2008), 437-446

We define elementary automorphisms of the $n$-dimentional vector group over an algebraically closed field of positive characteristic and show that they generate the automorphism group of the vector group. We also give a necessary and sufficient compu
