Query: Collective Dynamics of Random Polyampholytes   We consider the Langevin dynamics of a semi-dilute system of chains which are
random polyampholytes of average monomer charge $q$ and with a fluctuations in
this charge of the size $Q^{-1}$ and with freely floating counter-ions in the
surrounding. We cast the dynamics into the functional integral formalism and
average over the quenched charge distribution in order to compute the dynamic
structure factor and the effective collective potential matrix. The results are
given for small charge fluctuations. In the limit of finite $q$ we then find
that the scattering approaches the limit of polyelectrolyte solutions.
