(Non)uniqueness of critical points in variational data assimilation
Graham Cox
In this paper we apply the 4D-Var data assimilation scheme to the initialization problem for a family of quasilinear evolution equations. The resulting variational problem is non-c…

The essential spectrum of the 2D Euler operator
Graham Cox
Even in two dimensions, the spectrum of the linearized Euler operator is notoriously hard to compute. In this paper we give a new geometric calculation of the essential spectrum fo…
