One-dimensional model equations for hyperbolic fluid flow. (English) Zbl 1381.35135
Summary: In this paper we study the singularity formation for two nonlocal 1D active scalar equations, focusing on the hyperbolic flow scenario. Those 1D equations can be regarded as simplified models of some 2D fluid equations.
