| Research Abstract |
1. We established existence and uniqueness results of viscosity solutions for nonlinear partial differential equations involving nonlocal terms. such nonlocal terms arise in the Hamilton-Jacobi-Bellman equations associated with the dymnamical systems with jumps.
2. We investigated the blow-up property or time global existence of the solutions for Keller-Segel systems. These systems are mathematical models of chemotaxis.
3. We obtained existence results of radially symmetric nodal solutions for semilinear elliptic equations. We also proved norm estimates of these solutions.
