This is the easiest question i have. I can't believe it is so difficult. It is not like i am asking you to solve the problems. =20 There must be some important open problems in ordinary category theory. There are plenty of them in the theory of algebras and in representation theory=2C so there should be more of them in category the= ory. =20 Especially if you broaden the boundaries a bit of what ordinary category th= eory is. Take for instance: model categories=2C categorical logic=2C categorical quantization=2C topos theory-locales-sheaves. But i had originally pure category theory in mind. =20 Best regards Rafael Borowiecki [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
