A theorem of Gekeler compares the number of non-isomorphic automorphic representations associated with the space of cusp forms of weight $k$ on~$\Gamma_0(N)$ to a simpler function of $k$ and~$N$,...

#### A coarse Cheeger inequality for 1-forms

##### Mark A. Stern (Duke University, Mathematics)

119 Physics

Motivated by questions about the spectral geometry of hyperbolic manifolds, arising in number theory, we seek a lower bound for the first nonzero eigenvalue of the Laplace Beltrami operator on 1-forms...

#### A Variational Perspective on Wrinkling Patterns in Thin Elastic Sheets

##### Robert V. Kohn (New York University, Courant Institute of Mathematical Sciences)
Tuesday, March 19 - 3:15 pm
Gross Hall 103

The wrinkling of thin elastic sheets is very familiar: our skin wrinkles, drapes have coarsening folds, and a sheet stretched over a round surface must wrinkle or fold.

What kind of...

Let C be an algebraic curve over Q, i.e., a 1-dimensional complex manifold defined by polynomial equations. A celebrated result of Faltings implies that all algebraic points on C come in families of...
