Surjectivities, octonions and differential Galois theory

Research output: Contribution to journalArticlepeer-review


We provide an explicit description of the torsors associated to the three groups related to the octonions—the exceptional Lie group G2 and the spin groups Spin7 and Spin8—and construct generic differential Galois extensions for those groups.
