Teaching:

         In Fall 2014,   I will teach Math 3340, Introduction to Fixed Income Mathematics. This course provides
an introduction to the theory of interest and the analysis of loans
, bonds and leverage
It covers much of the theory required for one of the introductory actuarial exams. The prerequisite is calculus 2 and an ability to use Excel spreadsheets is expected.   For more information about these  courses and a listing of courses taught in recent years please  select the  Teaching  link above.

Research Interests:

             My research centers on the mathematical analysis of elliptic boundary value problems; especially eigenvalue problems and the  dependence of solutions on boundary data. Recently I have worked extensively on questions about Steklov eigenproblems and the representations of solutions of boundary value problems.  The topics I am interested in generally arise from  questions about the analysis of problems in fluid mechanics or in classical (non-relativistic) electromagnetic or gravitational fields.

          Recent papers have proved new results about harmonic functions and fields, boundary values (traces) of Sobolev functions, the representation of solutions of boundary value problems in exterior regions, the existence and properties of scalar and vector potentials and the well-posedness of  div-curl systems  that arise in either electromagnetic field theory or in fluid mechanics.

           Many of these results followed from the use of variational methods and principles and functional analysis including topics such as Reproducing Kernel Hilbert Spaces. The results have often depended on proving new inequalities and developing special representation results. Recently I proved new extensions of the Sobolev imbedding theorems for 3-d fields where integrability conditions are imposed on the Laplacian of a potential - but not on the function itself. This is the physical  situation for gravitational and electrostatic potentials.

          Another continuing research interest is in the theory of potentials for various classes of 3-dimensional vector fields when various types of boundary conditions are imposed.

        This research is currently supported by NSF award DMS 1108754 to study "Steklov spectra and Div-curl analysis".   Maxwell's equations are the most important examples of div-curl systems. See the link to Research for more information. 

      The work on these issues is theoretical mathematics, involving functional analysis and variational principles. It  does not involve  computational studies  and I do not have paid positions available for  programmers.

Research Students and Projects:    

      Here is a listing of  Ph.D. graduates whose theses I  have supervised. Currently Juan F. Lopez and Pablo Lopez are pursuing research projects with me. I have supervised many M.S. theses and some undergraduate honors students on a variety of mathematical  topics. If you are interested in studying  problems that involve partial differential equations or the calculus of variations - especially ones that arise from applications - feel free to contact me about possible projects.

 Editorial:

        Currently I am on the editorial board of the SIAM Journal of Mathematical Analysis (SIMA).   For information on SIMA please go to the SIAM website www.siam.org

        I am also on the board of Nonlinear Analysis and Differential Equations, published by Hikari Press and of the  Electronic Problems section, SIAM Review.

        This section associated with SIAM Review welcomes unsolved problems in applied and applicable mathematics. Contributors should send proposed problems to Cecil C Rousseau. If you can solve posted problems please let the proposer and SIAM know about your solutions.
