In this extended abstract, we present recent results on local and global gradient estimates of different geometric types for positive solutions to a nonlinear parabolic equation on a smooth metric measure space whose underlying metric and potential evolve in time. We present some applications, including parabolic Harnack inequalities and Liouville-type theorems and discuss some related examples.

摘要

In this extended abstract, we present recent results on local and global gradient estimates of different geometric types for positive solutions to a nonlinear parabolic equation on a smooth metric measure space whose underlying metric and potential evolve in time. We present some applications, including parabolic Harnack inequalities and Liouville-type theorems and discuss some related examples.
