Málek, J. (ed.) et al., Advanced topics in theoretical fluid mechanics. Lectures of the 5th Winter School on mathematical theory in fluid mechanics, Paseky nad Jizerou, Czech Republic, December 6-14, 1997. Harlow: Longman. Pitman Res. Notes Math. Ser. 392, 118-146 (1998).
This lecture note deals in details with the transport equation \(\lambda x+w. \nabla x+gx=f\), \(\lambda\in\mathbb{R}\), \(w,g\) and \(f\) are given functions on a given domain \(\Omega\). The main issues herein considered are the following ones. After a careful description of the function spaces in which the problem is considered, one states existence theorems for strong solutions and for weak solutions and studies the asymptotic properties of \(L^q\)-solutions. Finally, some results are stated on the transport equation in the divergence form.
