Geometric Rigidity Theory is concerned with the study of barjoint frameworks and related constraint systems of geometric objects. The area can be traced back to classical work of Euler, Cauchy and Maxwell on the rigidity of polyhedra and skeletal frames. However in recent years the subject has become particularly active, drawing on diverse areas of mathematics and engaging with a growing range of applications. The activity is driven in part by the solution of some longstanding open problems, such as the socalled Molecular Conjecture, and the determination , of the generic nature of global rigidity, and by new connections with other mathematical areas, such as matrix completion theory or machine learning. Impetus in the area has also come from new themes such as constraint systems with pointgroup or crystallographic symmetries and constraint systems in general normed linear spaces. Both the generic combinatorial theory and symmetric geometric theories are flourishing and in recent years the subject in general has increased its international visibility as an active research area.
The workshop will bring together researchers in order to advance the subject of Geometric Rigidity through expositions of recent results, through consultations between participants and through ensuing disseminations in research journals.
Details regarding participation in the workshop will appear here in due course.
Arrangements
The workshop will begin with registration on Monday morning 30 May (08:3009:00) and close around 13:00 on Friday 3 June 2016. Please take these timings into account when booking your travel.
Participation
Invited delegates were sent an emailed invitation from ICMS, on behalf of the Scientific Organisers, at the beginning of March.
Registration
There will be a £70 registration fee for this workshop.
 Payment can be made on arrival at ICMS  at Registration we will accept cash, credit/debit card payments and sterling cheques (payable to “HeriotWatt University”). Unfortunately, we do not yet have an online payment system at ICMS. If you wish to pay by credit/debit card, please complete the form (available in the link below) and bring the completed form to Registration.
Venue and Talks
The workshop will be held at 15 South College Street, Edinburgh. You may also find this map useful for the workshop. All lectures will be held in the Newhaven Lecture Theatre. The Lecture Theatre is equipped with a data projector, computer, visualiser (the new generation of overhead projectors) and two blackboards. The projector and one board may be used simultaneously. It is best to bring your presentation on a memory stick to use in our ICMS computer. Alternatively, it is possible for you to use your own laptop with our dataprojector, but please be aware that you may have to alter your laptop resolutions/settings.
Travel
Information about travel to the UK and Edinburgh is available here.
Please note that it is your responsibility to have adequate travel insurance to cover medical and other emergencies (volcanic ash disruptions) that may occur on your trip.
A taxi directly from the airport will cost approximately 16.00 to 20.00 GBP to the city centre for a oneway journey. There is also a bus service direct from the airport to the city centre which will cost 4.00 single or 7.00 GBP return  the Airlink 100. This is a frequent service (every 10 minutes during peak times) and will bring you close to Waverley Railway Station, only a short walk to the accommodation and the workshop venue (see map in 'Venue' section above).
Lothian buses charge £1.60 for a single, £4.00 for a day ticket. Please note that the exact fare is required and no change is given.
If travelling by train, please note that Edinburgh has several railway stations  Waverley Railway Station being the main station and closest to the workshop venue at 15 South College Street. If you alight at Edinburgh Waverley, the workshop venue is an easy 10 minute walk over North and South Bridge. The other railway stations are Haymarket and Edinburgh Park at the West End of the city centre.
UK Visas
If you are travelling from overseas you may require an entry visa. A European visa does not guarantee entry to the UK. Please use this link to the UK Visas site to find out if you need a visa and if so how to apply for one.
Accommodation
ICMS will organise accommodation for all invited participants
Catering
The workshop grant will cover refreshments throughout the event, lunch on three days, an informal wine reception and a workshop dinner.
Dinner
There will be a workshop dinner on Thursday 2 June at Blonde restaurant , 75 St.Leonard's Street, Edinburgh at 19:00.
Public Lecture
On Tuesday 31 May, Patrick Fowler (University of Sheffield), will give a Public Lecture (title and abstract below). Doors will open to the Public at 17.30, with the Lecture beginning at 18.00. The Public Lecture will be followed by an informal wine reception in the Chapterhouse, Level 1, at ICMS from 19.0020.00. Seats have been reserved in the Lecture Theatre for all the workshop participants so there is no need for you to book a seat.
'Symmetry in chemistry and engineering: Maxwell still going strong at 185'
The ideas of James Clerk Maxwell, a giant of 19th century science, are still helping to make new links between research on structures as small as molecules or as big as bridges. When Maxwell's ideas are combined with consideration of symmetry, engineers, and chemists can learn something from each other about structures that don't fall down, toys, viruses and polyhedra that change shape, and materials that get fatter when stretched. This talk will discuss some of these developments, with a minimum of mathematics and a maximum of pictures.
Programme
Please note that this is a Provisional Programme and may be subject to alteration.
