This page contains  a list of selected publications with some brief abstracts and also preprints that you can download in dvi, postscript or pdf format. Comments are greatly appreciated. This material is based upon work supported by the National Science Foundation under various grants.

One of my interests earlier on was in L2 Carleman estimates  and unique continuation for pde's, as well as
their applications in control theory. I have collected together those papers in the Unique  Continuation Page.
Other more recent papers on unique continuation dealing with Lp Carleman estimates are listed below.

Following are some selected published papers, as well as all the new preprints.
