Synopsis

Often for the purposes of computations we work with discretizations
of continuous objects, but conceptually it is usually the continuous framework
that has a physical interpretation. In this talk we ask the question: What are the
continuous analogues of matrix factorisations? The answer we develop involves
bivariate functions and an iterative variant of Gaussian elimination, leading to
a test for a non-negative definite kernel and a definition for a triangular
quasimatrix (a matrix whose columns are functions).
