## Regular value theorem in a fractal setting and regularity of Fourier integral operator

Start: | |
---|---|

End: | |

Venue: | DM 409A |

Alex Iosevich Abstract: The classical regular value theorem says that if f: X -> Y is an immersion, where X,Y are smooth manifolds of dimension n,m , n>m , respectively, then the set {x in X: f(x)=y } is either empty or is an n-m dimensional sub-manifold of X . We shall see that a suitable analog of this result is available if a manifold X is replaced by a set of sufficiently large Hausdorff dimension and the function f satisfies a "rotational curvature" condition.

Prof. Lotfi Hermi, Univ. of ArizonaTitle: Max-to-Mean Ratio Bounds for the Fundamental Eigenfunction of theDirichlet Laplacian DM 409A: Thurs Mar 31, 3:30pmAbstract: Max-to-Mean ratio for the fundamental eigenfunction of the DirichletLaplacian was developed by Payne-Stakgold, and Payne-Rayner in theearly 1970s in the context of shape optimization, with applications inmind. It is a means of gauging various norms of this eigenfunction, andfalls in a class known as ``reverse H"older inequalities''.

Venue: | DM 409A |

Zhijian Wu, Prof. and Chairperson at University of AlabamaTitle: Optimal Strategy for Certain Hedging ProblemAbstract: Under the constraint of terminal risk, we search for an optimal deterministic strategy to reduce the running risk in hedging a long-term commitment with short-term futures contracts. An explicit solution is given if the underlying stock follows the simple stochastic differential equation: $dS_t =mu dt + sigma dB_t$, where $B_t$ is the standard Brownian motion.

See you TuesdayLauraTitle: Developments of level set method in high frequency wave propagationAbstract: Due to high computational cost in direct simulation of high frequency wave propagation, semi-classical approximation is usually needed. However, the resulting effective equations have finite time singularity. Unlike the viscosity solution, multi-valued solution is relevant in wave propagation context.
