PhD student position in proof theory, Bath (England), Deadline: 29 Mar 2020

** PhD position in proof theory at the University of Bath

EFFICIENT AND NATURAL PROOFS AND ALGORITHMS

Proofs and algorithms are everyday objects in our discipline, but they are 
still very mysterious. Suffice to say that we are currently unable to 
decide whether two given proofs or two given algorithms are the same; this 
is an old problem that dates back to Hilbert. Also, proofs and algorithms 
are intimately connected in the most famous open problem in mathematics: P 
vs NP.

We make progress by trying to unveil the fundamental structure behind 
proofs and algorithms, what we call their semantics. In other words, we 
are interested in the following questions:

What is a proof?
What is an algorithm?
How can we define them so that they have efficient and natural semantics?

The questions above are interesting in their own right but answering them will enable technological advances of great impact on society and the economy. For example, it will be possible to build a worldwide, universal tool for developing, validating, communicating and teaching mathematics. Also, quickly producing provably bug-free and secure software will become possible, so solving one of the most complex and important open engineering problems.

To understand proofs and algorithms, we create new mathematics starting 
from proof theory and semantics. The methods we use are mostly discrete, 
algebraic and combinatorial, but there is a growing geometrical component. 
The recent advances which our methods are mostly based on are linear 
logic, game semantics and deep inference. You can find more information at 
<http://alessio.guglielmi.name/res/cos/>.

Our group is very well-financed via several grants. Thanks to our 
international relations, working with us means having a multicultural 
experience with all the researchers at the forefront of this worldwide 
research effort. As a result, all our graduates work and publish at the 
highest level. For example, one of our recent PhDs, Anupam Das, has won a 
prestigious UKRI Future Leaders Fellowship in 2019, worth 1.5M. The 
facilities at the University of Bath are outstanding and the city is so 
beautiful that UNESCO recognises it as a World Heritage Site.
