Wednesday, 7 December 2016: NODES Seminar, Durham

Posted on

General meeting of all members of NODES and their PhD students.

Location:

Pemberton Building, room PG21

Timetable:

14.00-14.45 Max Gadouleau (Durham, CS): An introduction to the theory of Finite Dynamical Systems
14.45-15.30 Tea/Coffee break
15.30-16.15 Evgenios Kakariadis (Newcastle, Maths): Operator algebras associated with subshifts

Max Gadouleau: An introduction to the theory of Finite Dynamical System

Abstract: We are interested in complex networks of interacting entities (such as genes, neurons, persons, computers, etc.), where each entity has a finitely valued state and a function which updates the value of the state.

Oleg Dolomanov (Durham, OLexSys Ltd): Maths in crystal structure analysis

Time and Location:

13:00 in CM221 (Durham)

Abstract: I will give a short introduction into how and why chemists get to the crystals, how the structures are solved and analysed. It will give some insight into practical use of maths in material sciences.

Peter Jorgensen (Newcastle, Maths): SL_2-tilings, infinite triangulations, and continuous cluster categories

Time and Location:

13:00 in CM221 (Durham)

Abstract:

An SL_2-tilings is an infinite grid of positive integers such that each adjacent 2×2-submatrix has determinant 1. These tilings were introduced by Assem, Reutenauer, and Smith for combinatorial purposes.
