Coordinate rings on symmetric spaces

Abstract Let $$G_k$$ G k be a connected reductive group over an algebraically closed field k of char $$\ne 2$$ ≠ 2 . Let $$\theta _k$$ θ k be an algebraic group involution of $$G_k$$ G k and denote the fixed point subgroup by $$K_k$$ K k . We construct an integral model for the s...
