Research
The general areas of my research are ordinary- and partial-differential equations and functional analysis with emphasis on variational methods for linear and non-linear boundary-value problems. A particular interest of mine has been in the existence and uniqueness questions for a class of non-linear elliptic boundary-value problems that arise in mathematical physics. Another interest has been in boundary-value and eigenvalue problems for the biharmonic operator. Results obtained here pertain to the bending and vibration of a clamped plate and to stationary Stoke's flow in the plane.
