Standard bases for coordinate rings of cotangent varieties
We extend the results of the Standard Monomial Theory to the cotangent variety of the Grassmannian, $TGrass(k,n)$. We exhibit a standard basis in terms of triples of tableaux. We are also able to show that $TGrass(k,n)$ is arithmetically Cohen-Macaulay and normal in all characteristics. Results on C...
