Program
The aim of this course is to introduce the audience to modern techniques in harmonic analysis with a special emphasis on the underlying symplectic symmetries; open problems will be discussed. We will give applications to time-frequency analysis and to mathematical quantization problems. A few topics we will address are the following:• Preliminaries on time-frequency analysis and related function spaces• The metaplectic representation of the symplectic group;• Maslov and Conley-Zehnder indices, applications to symplectic and metaplectic isotopies;• Weyl pseudodifferential calculus and the Wigner formalism;• Positivity properties of trace class operators;• Born-Jordan pseudodifferential operators; open problems.Suggested readings and bibliography
