Jan Willem Klop

Jan Willem Klop (born 1945) is a professor of applied logic at Vrije Universiteit in Amsterdam. He holds a Ph.D. in mathematical logic from Utrecht University. Klop is known for his work on the Algebra of Communicating Processes, co-author of TeReSe and his fixed point combinator
Yk = (L L L L L L L L L L L L L L L L L L L L L L L L L L)
where
L = λabcdefghijklmnopqstuvwxyzr. (r (t h i s i s a f i x e d p o i n t c o m b i n a t o r))
Klop became a member of the Royal Netherlands Academy of Arts and Sciences in 2003.
