Query: Critical behavior of nonequilibrium models with infinitely many
  absorbing states   I study the critical behavior of a two-dimensional dimer-trimer lattice
model, introduced by K\"{o}hler and ben-Avraham [J. Phys. A {\bf 24}, L621
(1991)], for heterogeneous catalysis of the reaction
$\frac{1}{2}A_{2}+\frac{1}{3}B_{3} \rightarrow AB$. The model possesses
infinitely many absorbing states in which the lattice is saturated by adsorbed
particles and reactions cease because only isolated vacancies are left. Results
for various critical exponents show that the model exhibits the same critical
behavior as directed percolation, contrary to earlier findings by K\"{o}hler
and ben-Avraham. Together with several other studies, reviewed briefly in this
article, this confirms that directed percolation is the generic universality
class for models with infinitely many absorbing states.
