S L 2 , the cubic and the quartic

Yannis Y. Papageorgiou (1998)

Annales de l'institut Fourier

We describe the branching rule from S p 4 to S L 2 , where the latter is embedded via its action on binary cubic forms. We obtain both a numerical multiplicity formula, as well as a minimal system of generators for the geometric realization of the rule.

Some results on the kernels of higher derivations on k[x,y] and k(x,y)

Norihiro Wada (2011)

Colloquium Mathematicae

Let k be a field and k[x,y] the polynomial ring in two variables over k. Let D be a higher k-derivation on k[x,y] and D̅ the extension of D on k(x,y). We prove that if the kernel of D is not equal to k, then the kernel of D̅ is equal to the quotient field of the kernel of D.
