review text: We investigate numerically the nonlinear dynamics of a gas bubble close to an inclined wall. The fluid is assumed to be inviscid and incompressible, and the flow irrotational. A time-integration boundary integral method is used to solve the Laplace equation for the velocity potential. Improvements to the previous research on this subject are made in the surface triangulation of the initial spherical bubble, the integration of the influence coefficients, the calculations of the normal vector and tangential velocity vector at a node, the time integration scheme, etc. Comparisons with earlier results demonstrate the robustness and accuracy of the present method.
