Nonlocal-to-local convergence of the -Biharmonic evolution equation with the Dirichlet boundary condition
Kehan Shi, Yi Ran
This paper studies the nonlocal -biharmonic evolution equation with the Dirichlet boundary condition that arises in image processing and data analysis. We prove the existence an…
