The 21st British Colloquium for Theoretical Computer Science (BCTCS) will be held at the University of Nottingham from 22nd to 24th March 2005. The purpose of BCTCS is to provide a forum in which researchers in theoretical computer science can meet, present research findings, and discuss developments in the field. It also aims to provide an environment in which PhD students can gain experience in presenting their work, and benefit from contact with established researchers.


Scope

The scope of the colloquium includes all aspects of theoretical computer science, including algorithms, complexity, semantics, formal methods, concurrency, types, languages and logics. Both computer scientists and mathematicians are welcome to attend, as are participants from outside of the UK.

The abstracts of the talks will be published in the Bulletin of the European Association of Theoretical Computer Science (EATCS), as well as on the colloquium web site. Any auxiliary material which is made available by speakers, such as talk slides or a supporting paper, will also be included on the web site. The detailed programme is given below. Abstracts and slides are available here.

Invited and stream A talks will be held in Lecture Theatre 1 in The Exchange, stream B talks will be held in room A01 of the School of Computer Science, tea/coffee will be taken in the foyer of The Exchange, and all meals will be taken in The Atrium.

Location

The colloquium will be held on the Jubilee Campus of the University of Nottingham, which has won many awards for its design and environmental features.

Nottingham is centrally located in the UK, and is easily reachable by all forms of transport.

By car: Leave the M1 motorway at junction 25 or 26, and follow the route to the Jubilee Campus using this map. Enter the campus itself via the main entrance on Wollaton Road on this map, as the other entrance (on Triumph Road) is only accessible with an electronic pass. Tell the security staff at the main entrance that you are attending the BCTCS conference, and they will direct you to the free visitors car park nearby. Make sure not to park elsewhere, as all other spaces require a parking permit and are subject to stickering or clamping.

By train or bus: The Jubilee Campus is around 10 minutes by taxi from the train and bus stations in Nottingham city centre. Online timetables and booking are available for both trains and buses.

By plane: The campus is around 30 minutes by taxi from Nottingham East Midlands airport, which has direct scheduled flights to many European destinations. Those without a direct flight should be able to make the journey with a single change, or may prefer to fly to Birmingham, Manchester, or Heathrow airports and then take the train to Nottingham. If you will be flying to Nottingham please book your ticket as soon as possible, as most of the carriers are budget airlines whose cheap flights are very popular. Online timetables and booking are available for most flights, via the above links.

In case you require a taxi as part of your return journey, here are some local numbers:

Central Taxi: 0115 975 2222
DG Taxi: 0115 960 7607
County Taxi: 0115 942 5425


Accomodation

Full registration includes single en-suite accomodation in Newark Hall on the Jubilee Campus for the nights of Monday 21st, Tuesday 22nd and Wednesday 23rd March. Rooms are available from 3pm on the day of arrival, and must be vacated by 10am on the day of departure. Keys can be obtained from the porter at the entrance of Newark Hall.
