Semi-Classical Analysis For Nonlinear Schrodinger Equations

FREEDownload : Semi-Classical Analysis For Nonlinear Schrodinger Equations

Remi Carles, "Semi-Classical Analysis For Nonlinear Schrodinger Equations"
English | 2008 | ISBN: 9812793127 | 256 pages | PDF | 3 MB

Semi-Classical Analysis For Nonlinear Schrodinger Equations
These lecture notes review recent results on the high-frequency analysis of nonlinear Schredinger equations in the presence of an external potential. The book consists of two relatively independent parts: WKB analysis, and caustic crossing. In the first part, the basic linear WKB theory is constructed and then extended to the nonlinear framework. The most difficult supercritical case is discussed in detail, together with some of its consequences concerning instability phenomena. Applications of WKB analysis to functional analysis, in particular to the Cauchy problem for nonlinear Schredinger equations, are also given. In the second part, caustic crossing is described, especially when the caustic is reduced to a point, and the link with nonlinear scattering operators is investigated.
These notes are self-contained and combine selected articles written by the author over the past ten years in a coherent manner, with some simplified proofs. Examples and figures are provided to support the intuition, and comparisons with other equations such as the nonlinear wave equation are provided.
Contents: WKB Analysis: Preliminary Analysis; Weak Nonlinear Geometric Optics; Convergence of Quadratic Observables via Modulated Energy Functionals; Pointwise Description of the Wave Function; Some Instability Phenomena; Caustic Crossing: The Case of Focal Points: Caustic Crossing: Formal Analysis; Focal Point without External Potential; Focal Point in the Presence of an External Potential; Some Ideas for Supercritical Cases.

Econometrics of Financial High-Frequency Data
by Nikolaus Hautsch
English | 2011 | ISBN: 3642219241 | 386 pages | PDF | 5.46 MB

The availability of financial data recorded on high-frequency level has inspired a research area which over the last decade emerged to a major area in econometrics and statistics. The growing popularity of high-frequency econometrics is driven by technological progress in trading systems and an increasing importance of intraday trading, liquidity risk, optimal order placement as well as high-frequency volatility.
