Singularity theory and topology work with each other, and the collaboration has led to many rich connections with various  fields such as mathematical physics, symplectic and contact topology, surgery theory. Recently, many new connections have appeared. The purpose of this workshop is to bring together specialists in singularity theory and topology, to have them present new developments to support and extend these interactions and open new perspectives in singularity theory and new applications of topology to singularity theory, and to introduce these new directions to young researchers.

Arrangements

The workshop will begin with registration on Monday 20 July at 08.45 and close at 14.00 on Friday 24 July 2015.   Please take these timings into account when booking your travel. 

Participation 

All invited participants have been sent an emailed invitation from ICMS, on behalf of the Scientific Organisers.

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. 

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.

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 that may occur on your trip.

A taxi directly from the airport will cost approximately 20.00 GBP to the city centre for a one-way 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 and the workshop venue. 

Lothian buses charge £1.50 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 meeting venue is an easy 10 minute walk over North and South Bridge.  The other railway stations are Haymarket and Edinburgh Park but please note that these stations are at the West End of the city centre.

Accommodation 

ICMS will organise accommodation for all participants.

Public Lecture 

On Wednesday 22 July, Pierrette Cassou-Nogues 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 lecture will be followed by an informal wine reception in the Chapterhouse at ICMS from 19.00-20.00. Seats have been reserved in the lecture theatre for all workshop participants and so there is no need for participants to book a seat. 

Polynomials

Polynomials are simple mathematical objects involving addition, subtraction and multiplication. However, they have played and still play an important role in mathematics. We shall discuss some of their part in algebra and geometry. 

Catering

The workshop grant will cover refreshments throughout the event, lunch on four days, informal wine receptions on Monday and Wednesday evenings and a Workshop Dinner on Thursday evening.   

Wireless Access

Access to wifi via Eduroam is available throughout the building. If you are not registered with Eduroam you will be given instructions and a code for accessing the wireless network.  For those without laptops, there will also be a couple of computers available for you to check your emails.  

Registration Fee

A 70.00 GBP registration fee is payable.
