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…

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…

Lines on algebraic varieties

J. M. Landsberg

A variety is covered by lines if there exist a finite number of lines contained in passing through each general point. I prove two theorems. Theorem 1:Let
