Abstract We consider the harmonic map heat flow for maps$$\mathbb {R}^{2} \to \mathbb {S}^2$$. It is known that solutions to the initial value problem exhibit bubbling along a well-chosen sequence of times. We prove that every sequence of times admits a subsequence along which bubbling occurs. This is deduced as a corollary of our main theorem, which shows that the solution approaches the family of multi-bubble configurations in continuous time.more » « lessFree, publicly-accessible full text available January 1, 2026

We consider the equivariant wave maps equation , in all equivariance classes . We prove that every finite energy solution resolves, continuously in time, into a superposition of asymptotically decoupling harmonic maps and free radiation.more » « lessFree, publicly-accessible full text available December 3, 2025
