SPRINGER’S REGULAR ELEMENTS OVER ARBITRARY FIELDS
... hyperplanes H̄ := H ⊗k k̄ for reflections in G, that is, if v is not fixed by any reflection in G. Define c in G to be regular if it has a regular eigenvector v ∈ V , say with eigenvalue ζ ∈ k̄ × . It will be seen below (Corollary 7) that this implies c is also p-regular, that is, its multiplicative ...

modularity of elliptic curves
... It is easy to show that an elliptic curve with equation y2 = x3 + ax2 + bx + c has singularities if and only if f(x) = x3 + ax2 + bx + c has multiple roots, which is the same thing as saying that the discriminant of f is 0. Since only finitely many primes can divide the discriminant, there are only ...

Rationality of the quotient of P2 by finite group of automorphisms
... we consider the quotient P2k /N. Next, we G/N-equivariantly resolve the singularities of P2k /N, run the G/N-equivariant minimal model program [13] and get a surface X . Then we apply the same procedure to the surface X and the group G/N. This method does not work if the group G is cyclic of prime o ...
