             =  First-order system least squares (FOSLS), general talks
                about the methodology our research team has developed for
                solving a wide variety of partial differential equations.

             = First-order system least squares (FOSLS) and First-order
               system LL^t (FOSLLt), a general talk about these two
               methods that apply to the solution of a variety of partial
               differential equations. FOSLLt is a later version of FOSLS
               that applies to problems with reduced regularity and lower
               smoothness properties.
