Query: Global Entropy Solutions to Weakly Nonlinear Gas Dynamics   Entropy weak solutions with bounded periodic initial data are considered for
the system of weakly nonlinear gas dynamics. Through a modified Glimm scheme,
an approximate solution sequence is constructed, and then a priori estimates
are provided with the methods of approximate characteristics and approximate
conservation laws, which gives not only the existence and uniqueness but also
the uniform total variation bounds for the entropy solutions.
