Parabolic Dynamics and Renormalization - An Introduction

Explore parabolic dynamical systems through this comprehensive lecture series that introduces mathematical models describing "slow" chaotic evolution where nearby trajectories diverge polynomially in time. Delve into the fundamental concepts and recent advances in understanding parabolic dynamics, which lack the general theoretical framework available for hyperbolic and elliptic systems. Master key mechanisms and techniques central to studying these complex systems through self-contained presentations accessible to a wide mathematical audience. Examine renormalizable linear flows and their properties, investigating how these systems exhibit chaotic behavior under specific conditions. Study horocycle flows on compact hyperbolic surfaces and their time-changes, understanding their geometric and dynamical significance. Investigate the Heisenberg nilflow and nilflows on nilmanifolds, including their time-changes and applications in modern dynamical systems theory. Analyze smooth area preserving flows on surfaces, also known as locally Hamiltonian flows, and their role in understanding parabolic dynamics. Discover the importance of shearing phenomena and renormalization techniques throughout various classes of parabolic systems. Learn about connections between parabolic flows and mathematical physics, spectral theory, and Teichmüller dynamics. Gain insights into both classical results and cutting-edge research developments in this active area of mathematical research through detailed mathematical definitions and accessible explanations of complex dynamical properties.
