Hughes does research in the field of programming languages. He is a member of the functional programming group at Chalmers, and has written many influential research papers on the subject, including "Why Functional Programming Matters". [3] Much of his research relates to the language Haskell.
In type theory, the general idea of a type system in computer science is formalized into a specific algebra of types. For example, when writing f : X → Y {\displaystyle f\colon X\to Y} , the intent is that X {\displaystyle X} and Y {\displaystyle Y} are types , while the arrow → {\displaystyle \to } is a type constructor , specifically, the ...
In the Haskell programming language, arrows allow functions (represented in Haskell by -> symbol) to combine in a reified form. However, the actual term "arrow" may also come from the fact that some (but not all) arrows correspond to the morphisms (also known as "arrows" in category theory) of different Kleisli categories. As a relatively new ...
Applying fmap (+1) to a binary tree of integers increments each integer in the tree by one.. In functional programming, a functor is a design pattern inspired by the definition from category theory that allows one to apply a function to values inside a generic type without changing the structure of the generic type.
The "generic programming" paradigm is an approach to software decomposition whereby fundamental requirements on types are abstracted from across concrete examples of algorithms and data structures and formalized as concepts, analogously to the abstraction of algebraic theories in abstract algebra.

Concurrent Haskell is an extension to Haskell that supports threads and synchronization. [7] GHC's implementation of Concurrent Haskell is based on multiplexing lightweight Haskell threads onto a few heavyweight operating system (OS) threads, [8] so that Concurrent Haskell programs run in parallel via symmetric multiprocessing. The runtime can ...
