I am attaching a PDF of Alex and Alison's final presentation for ES 240. The topic is "Arterial Compliance and Disease."
ES 240 Problem Set #8, Problem #20 - Green's function of biharmonic operator is not positive definiteSubmitted by John Peter Whitney on Thu, 2007-12-06 23:44.
Professor Vlassak mentioned that last year every single person did a finite element project. He said he wanted to see more theory projects, so I decided to take him up on that.
I was browsing around one day and happened upon an article that explained that while the Green's function of the laplacian was positive definite, the biharmonic operator's Green's function is not. Physically, this has significance.
