Query: On semigroups of nonnegative functions and positive operators   We give extensions of results on nonnegative matrix semigroups which deduce
finiteness or boundedness of such semigroups from the corresponding local
properties, e.g., from finiteness or boundedness of values of certain linear
functionals applied to them. We also consider more general semigroups of
functions.
