Affine slice for the coadjoint action of a class of biparabolic subalgebras of a semisimple Lie algebra
Patrice Tauvel, Rupert W. T. Yu
In this article, we give a simple explicit construction of an affine slice for the coadjoint action of a certain class of biparabolic (also called seaweed) subalgebras of a semisim…

On the index of certain Lie algebras
Patrice Tauvel, Rupert W. T. Yu
We give an upper bound for the index of certain Lie algebras, called of seaweed type, introduced by V. Dergachev, A. Kirillov and D. Panyushev. We deduce from this a conjecture of…

Index and stable linear forms of Lie algebras
Patrice Tauvel, Rupert W. T. Yu
We characterize, in a purely algebraic manner, certain linear forms, called stable, on a Lie algebra. As an application, we determine the index of a Borel subalgebra of a semi-simp…
