On the infinitesimal rigidity of homogeneous varieties

J. M. Landsberg

Let $X \subset P^{N}$ be a variety (respectively a patch of an analytic submanifold) and let $x \in X$ be a general point. We show that if the projective second fundamental form of $X$ …

Is a linear space contained in a variety? - On the number of derivatives needed to tell

J. M. Landsberg

Let $X^{n} \subset C^{n + a}$ or $X^{n} \subset P^{n + a}$ be a patch of an analytic submanifold of an affine or projective space, let $x \in X$ be a general point, and let L^k be a linear sp…

On an unusual conjecture of Kontsevich and variants of Castelnuovo's lemma

J. M. Landsberg

Let $A = (a_{j}^{i})$ be an orthogonal matrix with no entries zero. Let $B = (b_{j}^{i})$ be the matrix defined by $b_{j}^{i} = \frac{1}{a _{j}^{i}}$ . M. Kontsevich conjectured that the rank of $B$ is nev…
