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…
Series of nilpotent orbits
J. M. Landsberg, L. Manivel, B. W. Westbury
We organize the nilpotent orbits in the exceptional complex Lie algebras into series using the triality model and show that within each series the dimension of the orbit is a linea…
Griffiths-Harris rigidity of compact Hermitian symmetric spaces
J. M. Landsberg
I show that any complex manifold that resembles a rank two compact Hermitian symmetric space (other than a quadric hypersurface) to order two at a general point must be an open sub…
Series of Lie Groups
J. M. Landsberg, L. Manivel
For various series of complex semi-simple Lie algebras $\fg (t)$ equipped with irreducible representations , we decompose the tensor powers of into irreducible factors…
