Spherical simplices generating discrete reflection groups
A. Felikson
Let be a simplex in and be a group generated by the reflections with respect to the facets of . We are interested in the case when the group is discrete. I…
Prolongation structure of the Krichever-Novikov equation
Sergei Igonin, Ruud Martini
We completely describe Wahlquist-Estabrook prolongation structures (coverings) dependent on u, u_x, u_{xx}, u_{xxx} for the Krichever-Novikov equation u_t=u_{xxx}-3u_{xx}^2/(2u_x)+…
Circles and Clifford Algebras
Vladlen Timorin
Consider a smooth map from a neighborhood of the origin in a real vector space to a neighborhood of the origin in a Euclidean space. Suppose that this map takes all germs of lines…
Boundary Value Problems on Manifolds with Fibered Boundary
A. Yu. Savin, B. Yu. Sternin
We define a class of boundary value problems on manifolds with fibered boundary. This class is in a certain sense a deformation between the classical boundary value problems and th…
Some amazing properties of spherical nilpotent orbits
Dmitri I. Panyushev
Let $\g$ be simple Lie algebra. We give a conceptual proof for the fact that the nilpotent orbits of height 3 are spherical. It is shown that if the highest root of $\g$ is fundame…
