As a motivation for the optimal control of PDEs,
we will present the
optimization problem of protein production based on gene expression
thanks to the messenger RNA (mRNA). There is currently an increased
interest for this type of technique, which however raises serious
difficulties for the mathematical / numerical analysis.
We will show how to express the original problem
as an optimal control problem for the Fokker-Planck
equation. The latter is a conservative, anisotropic parabolic PDE, with
degeneracies at the boundary and control through the
coefficients. We will discuss the well-posedness of this PDE
(in appropriate weighted spaces) and the approximation of
related optimal control problems by finite difference methods.
