Stable sampling and Fourier multipliers / Matei, Basarab (Université Paris Nord) ; Meyer, Yves (École Normale Supérieure de Cachan (Cachan, França)) ; Ortega Cerdà, Joaquim (Universitat de Barcelona)
We study the relationship between stable sampling sequences for band-limited functions in Lp(Rn) and the Fourier multipliers in Lp. In the case that the sequence is a lattice and the spectrum is a fundamental domain for the lattice the connection is complete. [...]

Volatility during the financial crisis through the lens of high frequency data : a realized GARCH approach / Banulescu-Radu, Denisa ; Hansen, Peter Reinhard ; Huang, Zhuo ; Matei, Marius
We study financial volatility during the global financial crisis and use the largest volatility shocks to identify major events during the crisis. Our analysis makes extensive use of high frequency (HF) financial data to model volatility and, importantly, to determine the timing within the day when the largest volatility shocks occurred. [...]
