Two footnotes to a theorem of Ray (
Markov processes)
Ray's theorem (
Ann. of Math.,
70, 1959) is the construction of a good semigroup (and process) from a Ray resolvent. The first ``footnote'' gives the construction of a second semigroup with nice properties from the left instead of the right side. The second ``footnote'' studies the filtration of a Ray process
