Jan Willem Klop (19 December 1945 – 28 September 2025) was a Dutch mathematician who was professor of applied logic at Vrije Universiteit in Amsterdam. He held 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[2] and his fixed point combinator[3]
- 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.[4] He died on 28 September 2025, at the age of 79.[5]
