Query: Asymptotics of semigroups generated by operator matrices   We survey some known results about operator semigroup generated by operator
matrices with diagonal or coupled domain. These abstract results are applied to
the characterization of well-/ill-posedness for a class of evolution equations
with dynamic boundary conditions on domains or metric graphs. In particular,
our ill-posedness results on the heat equation with general Wentzell-type
boundary conditions complement those previously obtained by, among others,
Bandle-von Below-Reichel and Vitillaro-V\'azquez.
