Tropical Mathematics & its Applications

Supported by the LMS

10th August 2016
 School of Mathematics, University of Manchester

Local Organiser: Marianne Johnson

A joint research group in tropical mathematics has been formed by researchers in UK mathematics departments at universities including Manchester, Birmingham, Warwick, Queen Mary and Swansea, with financial support from the London Mathematical Society. This page gives details of the next meeting, to be held in Manchester. Funds are available to support the attendance of UK-based postgraduate students.


* Alex Fink (QMUL)
* Marianne Johnson (Manchester)
* Sergei Sergeev (Birmingham)

Provisional programme

All talks will talk place in the Frank Adams room of the Alan Turing building in the School of Mathematics, University of Manchester. (See below for advice on how to get here.)

13:00 Marianne Johnson Face monoid actions and tropical hyperplane arrangements
14:00 Sergei Sergeev Bounds on the periodicity of max-plus matrix powers
15:00 Coffee
15:30 Alex Fink Flags of tropical linear spaces from matroids over a valuation ring
16:30 Close
17:00 Dinner
We plan to go for an early dinner shortly after the last talk, somewhere near to the train station. It would be helpful if you could let Marianne know if you intend to join us for dinner.


There are no registration fees, but it would be helpful if you could confirm your attendance by email ( Financial support for UK-based postgraduate students is awarded on a first come first served basis; please give an estimate of your travel costs when confirming your attendance.

Directions from Manchester Piccadilly station

Walking from Manchester Piccadilly to the Alan Turing Building should take around 20 mins. Leave the station by the Fairfield Street exit (head down the escalators or lift from the main concourse) which brings you out at a big road junction. Cross both main roads, and go along a smaller road (Granby Row) to the left of the Bull's Head pub. Keep straight on, as the road becomes a pedestrian walk and then a road again, and at the phoneboxes turn left onto Sackville Street. Go under the railway bridge and continue under a bridge between buildings, and where the road bends off to the right, follow the left-hand pavement which becomes a footpath and goes through an underpass. Afterwards, keep left under the motorway flyover (avoiding a deeper underpass ahead) before bearing right (avoiding yet another underpass to the left). After very carefully crossing the motorway sliproad, you find yourself on Brook Street. Walk down this (away from the flyover). At the intersection with Grosvenor Street, cross both roads and then continue along (now Upper) Brook Street on the opposite side. Cross the next side-road (Booth Street East, carefully again!), continue past the Aquatics Centre car park and then the Alan Turing Building is on your right. To get into the building, go into the walkway after the second "finger" and then the doors are on your right.
