# The Blowtorch Theorem

#### The Blowtorch Theorem

- Event time: 11:30am until 12:30pm
- Event date: 6th February 2019
- Speaker: Mr Emil Mallmin (School of Physics & Astronomy, University of Edinburgh)
- Location: Room 2511, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

I will discuss the "Blowtorch theorem" (BT) based on the article "Maes & Netocny, Ann. Henri Poincaré 14 (2013)". In the framework of Markov jump processes, an equilibrium steady state is determined by the energy/entropy part of the transition rates. A nonequilibrium steady state, on the other hand, depends also on the kinetic part. The BT gives a condition suggestive of the Comparison Hypothesis (as discussed last week), for when the effect of kinetics is in a sense strong. We will review Kirchoff’s graph-theoretical method of solving the master equation, and use it to derive the Blowtorch theorem.
