Perhaps the most famous equation in science is E = mc2; it also represents one of the best-known scientific insights. But why does Einstein’s equation about the conservation of energy enjoy such popularity? Is it because it is easily and instinctively understood, or because it is widely taught in schools?

Reasoning about side effects and aliasing is the heart of verifyingimperative programs. Unrestricted side effects through one refer-ence can invalidate assumptions about an alias. We present a newtype system approach to reasoning about safe assumptions in thepresence of aliasing and side effects, unifying ideas from referenceimmutability type systems and rely-guarantee progr...

Case is defined by the positive values [+H(ighest) R(ole)], [+L(owest) R(ole)], which are assigned to the Th-roles according to their relative position on the Th-role hierarchy (itself a projection of semantic form). (25) a. [+HR] is assigned to the highest role. b. [+LR] is assigned to the lowest role. Our notion of abstract Case resembles GB’s in that it is a syntactically assigned feature co...
