Effects and coeffects are two general, complementary aspects of program behaviour. They
roughly correspond to computations which change the execution context (effects) versus …

Logic is the study of reasoning. Typically, it proceeds in terms of inferring a conclusion from
established premises. The systematic use of symbolic and mathematical techniques to …

Existing approaches for statically enforcing differential privacy in higher order languages
use either linear or relational refinement types. A barrier to adoption for these approaches is …

The polymorphic RPC calculus allows programmers to write succinct multitier programs
using polymorphic location constructs. However, until now it lacked an implementation. We …

Graded types are a class of resourcefultypes which allow for finegrained quantitative
reasoning about data-flow in programs. Tracing their roots from linear types, the use of …
