The workshop will bring together pure mathematicians and control engineers with an interest in complex variable methods. The unifying theme is the use of several complex variables as a tool for representing and analysing the uncertainty of models used in engineering design, particularly in the design of robust automatic controllers. Engineers often represent modelling error as a linear fractional transform of an unknown element of a structured uncertainty class; then the problem of designing controllers that are robust with respect to uncertainty leads to questions that are in the territory of operator theorists and specialists in several complex variables. One strand is the engineering problem of mu-synthesis, which has led to the study of certain inhomogeneous domains, the symmetrised polydisc and the tetrablock, which enjoy a rich function theory and operator theory.
The workshop will encourage the sharing of problems and results between control engineers, operator theorists and specialists in several complex variables. There will be a public lecture on Tuesday 22 July given by Professor Malcolm Smith.
This workshop is generously supported by EPSRC, the School of Mathematics and Statistics at Newcastle University, and the London Mathematical Society.
Arrangements
It is anticipated that the workshop will commence with Registration on Monday morning 21 July and close around midday on Friday 25 July 2014. Please take these timings into account when organising your travel to the workshop.
Participation
Participation is by invitation only. Invitations were emailed mid-February 2014.
Venue
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 data projector, but please be aware that you may have to alter your laptop resolutions/settings.
Travel
**Please note that the Glasgow 2014 Commonwealth Games start on 23rd July and it is advisable to book travel as soon as possible, as availability nearer the time may be limited, and costs will be higher. **
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 to 25.00 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 GBP 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 £1.50 for a single, £3.50 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 three 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 stations are Haymarket and Edinburgh Park at the West side of the city).
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.
Participants who require a visa for entry to the UK should contact ICMS as soon as possible.
Accommodation
Most participants will be staying at Pollock Halls of Residence:
Masson House, Pollock Halls of Residence, The University of Edinburgh, 18 Holyrood Park Road, Edinburgh EH16 5AY
0800 028 7118 (UK only) - +44 (0)131 651 2189
Pollock Halls is about a 20-25 minute walk from ICMS.
Catering
The workshop grant will cover refreshments throughout the event, lunch on three days, an informal wine reception and a workshop dinner.
Wireless Access
The workshop venue, 15 South College Street, has wireless access throughout. On arrival at Registration 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 by all.
- Payment can be made on arrival at ICMS - at Registration we will accept cash, credit/debit card payments and sterling cheques (payable to “Heriot-Watt University”). Unfortunately, we do not yet have an on-line 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.
- Alternatively, if you wish to pay in advance, please print out the credit/debit card payment form and complete by filling in your details. As email is not secure, the completed form should be faxed to me using the fax number at the top of the form. The fax machine is in a locked room and your details will be kept securely until payment is taken. We also accept sterling cheques, made payable to “Heriot-Watt University” but sent to Diane Horberry, ICMS, 15 South College Street, Edinburgh, EH8 9AA. A receipt will be emailed to you.
