Direct and inverse scattering problem
for multi-channel scattering
(Abstract:
We study scattering problem for a system
which consists of a finite number of semi-infinite channels
connected through a bounded scatterer.
This is a joint work with V. Marchneko.) |

Francesco Fassò |
Noetherian first integrals of nonholonomic systems
(Abstract:
The relation between symmetries and conserved quantities for
nonholonomic mechanical systems is not yet well understood.
We review the problem and describe some recent results,
focusing on the question of the (non)existence of first integrals which,
like the standard momentum map for the holonomic case,
have the ‘Noetherian’ property,
that is, they are first integrals of any nonholonomic system
with invariant Hamiltonian.) |

Sheehan Olver |
Multivariate highly oscillatory integration
(Abstract:
The aim of this talk is to describe several methods for numerically approximating
the integral of a multivariate highly oscillatory function.
We begin with a review of the asymptotic and Filon-type methods
developed by Iserles and Nørsett.
Using a method developed by Levin as a point of departure
we will construct a new method
that uses the same information as a Filon-type method,
and obtains the same asymptotic order, while not requiring moments.
This allows us to integrate over nonsimplicial domains,
and with complicated oscillators.) |
