**Title**: Gradient catastrophes for Burgers equation on a finite interval. Numerical and qualitative study
**Abstract**:

We consider initial value-boundary problem (IVBP) for the Burgers equation

on a finite interval:

.

The case of constant boundary conditions , and its asymptotics is of special interest here. For such a IVBP viscosity usually produces asymptotic stationary solution which is invariant for some subalgebra of the full symmetry algebra of the equation. But the evolution may also result in a stable gradient catastrophe.
