Fubini's Theorem in codimension two
J. M. Landsberg, Colleen Robles
We classify codimension two analytic submanifolds X of projective space having the property that any line through a general point p having contact to order two with X at p automati…
Legendrian varieties
J. M. Landsberg, L. Manivel
We investigate the geometry of Legendrian complex projective manifolds $X\subset\PP V$. By definition, this means is a complex vector space of dimension , endowed with a…
The sextonions and
J. M. Landsberg, L. Manivel
We fill in the "hole" in the exceptional series of Lie algebras that was observed by Cvitanovic, Deligne, Cohen and deMan. More precisely, we show that the intermediate Lie algebra…
A universal dimension formula for complex simple Lie algebras
J. M. Landsberg, L. Manivel
We present a universal formula for the dimension of the Cartan powers of the adjoint representation of a complex simple Lie algebra (i.e., a universal formula for the Hilbert funct…
On the ideals of secant varieties of Segre varieties
J. M. Landsberg, Laurent Manivel
We establish basic techniques for studying the ideals of secant varieties of Segre varieties. We solve a conjecture of Garcia, Stillman and Sturmfels on the generators of the ideal…
