Query: Geometric Flow of Bubbles   In this work we derive a class of geometric flow equations for metric-scalar
systems. Thereafter, we construct them from some general string frame action by
performing volume-preserving fields variations and writing down the associated
gradient flow equations. Then, we consider some specific realisations of the
above procedure, applying the flow equations to non-trivial scalar bubble and
metric bubble solutions, studying the subsequent flow behaviour.
