Abstract: Profile decomposition is an intriguing phenomenon for the critical energy harmonic flow. It is a natural question to ask which configuration of bubbles is possible in the decomposition. Inspired by the formal analysis of Fila-King for the critical heat equation, we construct global solutions for the harmonic map flow in the 1-equivariant class, with global growing, bounded and decaying dynamics.

This is joint work with Juncheng Wei and Yifu Zhou.
