Title of talk: On the Stability of Self-Similar Blow-Up for Nonlinear Wave Equations

One Of fundamental importance in studying nonlinear wave equations is the singularity development of the solutions.
Within the context of energy supercritical wave equations, a typical way to investigate singularity development is through the self-similar blowup.
