Research Abstract

I consider the evolution of the harmonic maps, called the harmonic map flows. In particular, I study the global existence and regularity of weak solutions of the harmonic map flows. I improve the regularity criterion for weak solutions and show the global existence of the dissipative wave equations, with applications to the wave maps.
