An Initial and Boundary Value Problem Modeling Fish-like Swimming

In this paper we consider an initial and boundary value problem modeling the self-propelled motion of solids in a bi-dimensional viscous incompressible uid. The self-propelling mechanism, consisting in appropriate deformations of the solids, is a simpli ed model for the propulsion mechanism of sh-like swimmers. The governing equations are composed of the Navier-Stokes equations for the uid, cou...

Light Front Quantisation as an Initial-Boundary Value Problem

In the light front quantisation scheme initial conditions are usually provided on a single lightlike hyperplane. This, however, is insufficient to yield a unique solution of the field equations. We investigate under which additional conditions the problem of solving the field equations becomes well posed. The consequences for quantisation are studied within a Hamiltonian formulation by using th...
