  • Title: On the regularity of time occupation functionals for Gaussian processes
  • Abstract:
We are interested in the order of Sobolev space $\mathbb{D}_{2}^{\alpha}$ for which Wiener functional functional $ \int_{0}^{t} \Lambda ( X_{s}, \dot{X}_{s} ) \mathrm{d}s $ belongs to, where $\Lambda$ is a Schwartz distribution on $\mathbb{R}^{2}$ and $X = (X_{t})_{t \in \mathbb{R}}$ is a centered stationary Gaussian process satisfying some conditions. This class of functionals cover the cases of time-occupational functionals and level crossings. Joint work with Marie Kratz.

　　　ウェストウィング6階談話会室
講演者：Marcin Marciniak (University of Gdansk, Poland)
タイトル：Introduction to Quantum Information Theory
アブストラクト：
Quantum Information Theory (QIT) is an exciting, young field which lies at the intersection of Mathematics, Physics and Computer Science. It emerged rapidly in last twenty years. QIT has sources in classical information theory but it seriously treats foundations of quantum theory also. 
Soon it turned out that some problems formulated in this theory are highly nontrivial. 
 
The aim of the series of talks is to present mathematics of QIT. Main mathematical tool come from linear algebra, functional analysis, operator algebra theory as well as probability theory. We will describe selected notions of QIT together with mathematics lying behind them.
