Abstract: The paper presents a systematic study of classical statistical inference
problems (parameter estimation and hypothesis testing) for random fields arising as
solutions of the one-dimensional nonlinear diffusion equation with random initial
data (the Burgers’ turbulence problem). This nonlinear, hydrodynamic-type partial
differential equation is an ubiquitous model in physics and engineering. This work
can be seen as part of a larger program of developing statistical inference tools for
complex stochastic flows governed by nontnvial, physically constrained dynamics.
