Webb31 maj 2016 · Yet mathematicians can still try to figure out an upper bound on how big a cap set can be — a number of cards guaranteed to hold at least one set. This question is one of the simplest problems in the mathematical field called Ramsey theory, which studies how large a collection of objects can grow before patterns emerge. WebbThe question for which theories the Shelah and Kim-Pillay strong types coincide is fundamental in model theory. This is known to be true in e.g. stable or supersimple theories, but remains a well-known open question in simple theories in general. This led us to the question for which theories the Ellis group is pro nite, which is also ... sandie shaw tell the boys
