## Doubly probabilistic representation for the stochastic porous media type equation.(English. French summary)Zbl 1387.35635

Summary: The purpose of the present paper consists in proposing and discussing a doubly probabilistic representation for a stochastic porous media equation in the whole space $$\mathbb{R}^{1}$$ perturbed by a multiplicative colored noise. For almost all random realizations $$\omega$$, one associates a stochastic differential equation in law with random coefficients, driven by an independent Brownian motion.
