The purpose of the paper is to give an a priori convergence estimate for the hp-adaptive boundary element method. The method is used to solve an exterior Hehnholtz boundary-value problem with the Robin's boundary condition in the three-dimensional space. The mathematical model describes an acoustic

## Abstract The integral equations arising from the Green's formula, applied to the twoβdimensional Helmholtz equation defined in a limited domain, are considered and the presence of instabilities in their numerical solution, when a real Green's function is adopted, is pointed out. A complete stud
This paper is a continuation of the work [9]. We prove the uniqueness result for global in time large solutions of dynamic equations to an inelastic model of material behaviour of metals in the two-dimensional case, provided a higher regularity of the solutions. Moreover, the +N-stability for p(2 of
