Dear all, I have been searching for several papers/preprints regarding monads, and algebraic theories, without much success. If anyone has a copy of one of the following papers, or knows where to find a copy, I would be very grateful to hear from you. (Unfortunately I do not have much information further than the title, author, and year, since I have come across these simply as citations.) - "A note on a construction of Kleisli" (Michael Barr, University of Illinois, 1965). - "J-adjonctions et J-monades" (Yves Diers, Universit?? de Lille, 1970). - "Relative Functorial Semantics, III: Triples vs. Theories" (Fred Linton, Banach Center (Warsaw), 1974). - "Clones, Cotriples and the Structure Semantics adjointness" (George Reynolds, Union College, 1975), the abstract for which can be found here: https://www.ams.org/journals/notices/197601/197601FullIssue.pdf. If anyone knows whether there was ever a "Relative Functorial Semantics, II" (the first in the series presumably being the 1969 paper "Relative functorial semantics: adjointness results"), I would also like to know. In addition, Fred Linton apparently gave two talks about algebraic theories a number of years after his papers on the subject. If anyone attended either of the following talks (presuming the talks were given) and recalls any of the content, I would be interested to hear. - "Triples vs. Theories???one last time" at Billfest, 1997. - "Triples vs. Theories as Yet another Yoneda Lemma" at either Octoberfest 2005 or StreetFest 2005. Many thanks, Nathanael [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
