Local solvability and blowup of the solution of the Rosenau-Burgers equation with different boundary conditions

We consider several models of initial boundary-value problems for the Rosenau-Burgers equation with different boundary conditions. For each of the problems, we prove the unique local solvability in the classical sense, obtain a sufficient condition for the blowup regime, and estimate the time of the solution decay. The proof is based on the well-known test-function method.
