WENG Suggested Problems for Logic and Proof The following problems are from Discrete Mathematics and Its Applications by Kenneth H. Rosen.Welcome. On behalf of our faculty, staff, and students, welcome to Department of Mathematics at CSU San Bernardino. We are excited about your interest in our programs and our campus. Formalize in propositional logic: In earlier times there existed an island whose inhabitants were either knights or knaves. A knight always tells the truth, while a knave always lies. Hedwig and Katrin lived on that Island.

Can such a barber exist? With all the wit and charm that have delighted readers of his previous books, Smullyan transports us once again to that magical island where knights always tell the truth and knaves always lie. Here we meet a new and amazing array of characters, visitors to the island, seeking to determine the natives’ identities.
