A multi-component coupled KPZ equation appears in fluctuating hydrodynamics.
The equation is ill-posed in general, and we need to introduce its approximation and renormalizations. We consider two types of approximations and investigate their limits by applying the paracontrolled calculus. The Cole-Hopf transform does not work for coupled equations.

This is joint work with Masato Hoshino.
