New question #141904 on DOLFIN: https://answers.launchpad.net/dolfin/+question/141904
Hi, I am looking for a way to implement an integral operator in Python/Dolfin of the following form: Carleman operator Q : L^2 -> L^2 Given: an integral kernel q(x,y), where q is symmetric q(x,y) = q(y,x) For u in L^2 the integral operator Q is given by [Qu](x) = \int q(x,y) u(y) dy In particular, I am interested in determing the eigenvalues and eigenfunctions of Q, i.e. Qu = \lambda u Thus, for a finite element approximation I need the matrix \int \int q(x,y) u(x) v(y) dy dx where u and v are the trial and test function, respectively. I am new to Dolfin and sorry if there already is an answer to this question. Thank you for any help!
