| Research Abstract |
Based on the method of functional analysis, the investigator has formulated nonlinear partial differential equations as evolution equations in abstract spaces. He has solved the related optimal control, parameter identification and stabilization problems by using the method of variation and the semi-group theory. As applications of the results to partial differential equations, he has studied the following five types of equations.
(1) First order nonlinear evolution equations. (2) Nonlinear wave equations.
(3) Second order evolution equations of Volterra type.
(4) Nonlinear equations of vibration with nonlocal terms.
(5) Coupled advection-diffusion equations.
