We will focus on the singularity formation and long time asymptotics. To be specific, there are two parts in the thesis. In the first part, we give a construction of log-log blow up solutions which blow up at m prescribed points simultaneously. In the second part, we show weak convergence to ground state for certain radial blow up solutions to NLS at well chosen time sequence. We also include a lecture note on concentration compactness. Concentration compactness is one of the main tool we use in the second part of the thesis.

Abstract: The mathematical nature of dispersion is the starting point of a very rich mathematical activity that has seen incredible progress in the last twenty years, and that has involved many different branches of mathematics: Fourier and harmonic analysis, analytic number theory, differential and symplectic geometry, dynamical systems and probability. In this talk I will give examples of these diverse directions and related open problems. Speaker: Gigliola Staffilani Massachusetts Institute of Technology Abby Rockefeller Mauzé Professor of Mathematics Gigliola Staffilani was named the Abby Rockefeller Mauzé Professor of Mathematics in 2007. She received the B.S. equivalent from the University of Bologna in 1989, and the S.M. and Ph.D. degrees from the University of Chicago in 1991 and 1995, respectively. Carlos Kenig was her doctoral advisor. Following a Szegö Assistant Professorship at Stanford, she had faculty appointments at Stanford, Princeton and Brown, before joining the MIT mathematics faculty in 2002. Professor Staffilani is an analyst, with a concentration on dispersive nonlinear PDEs. At Stanford, she received the Harold M. Bacon Memorial Teaching Award in 1997, and was given the Frederick E. Terman Award for young faculty in 1998. She was a Sloan fellow from 2000-02. In 2013 she was elected member of the Massachusetts Academy of Science and a fellow of the AMS, and in 2014 fellow of the American Academy of Arts and Sciences. -

On the Depth of Szemerédi's Theorem
1–13 10.1093/philmat/nku036 Philosophia Mathematica On the Depth of Szemerédi’s Theorem† Andrew Arana Department of Philosophy, University of Illinois at Urbana-Champaign, Urbana, Illinois 61801, U.S.A. E-mail: [email protected] ABSTRACT 5 Many mathematicians have cited depth as an important value in their research. How- ever, there is no single, widely accepted account of mathematical depth. This article is an attempt to bridge this gap. The strategy is to begin with a discussion of Szemerédi’s theorem, which says that each subset of the natural numbers that is sufficiently dense contains an arithmetical progression of arbitrary length. This theorem has been judged 10 deepbymanymathematicians,andsomakesforagood caseonwhichtofocusinanalyz- ing mathematical depth. After introducing the theorem, four accounts of mathematical depth will be considered. Mathematicians frequently cite depth as an important value for their research. A perusal of the archives of just the Annals of Mathematics since the 1920s reveals 15 more than a hundred articles employing the modifier ‘deep’, referring to deep results, theorems, conjectures, questions, consequences, methods, insights, connections, and analyses. However, there is no single, widely-shared understanding of what mathemat- ical depth consists in. This article is a modest attempt to bring some coherence to mathematicians’ understandings of depth, as a preliminary to determining more pre- 20 cisely what its value is. I make no attempt at completeness here; there are many more understandings of depth in the mathematical literature than I have categorized here, indeed so many as to cast doubt on the notion that depth is a single phenomenon at all.
