| Abstract: | The possibility of controlling the oscillations of a spherical gas bubble in an ideal incompressible liquid is subjected to
theoretical analysis. Liquid surface tension forces are not taken into account. The optimization process realizing a maximum
of the radius amplitude and a maximum of the gas pressure in the bubble for a given impulsive change of pressure at infinity
is considered. A shock-resonance bubble oscillation procedure giving stepwise pressure changes at the extrema of the radius
is constructed. This problem is of interest in connection with the investigation of cavitation erosion 1] and processes in
biological tissues 2–4].
