                   WORKSHOP ON MOLECULAR COMPUTING                   
                        December 14--15, 1998                        
                        I.I.T. Madras, Chennai                       


Molecular Computing or DNA Computing is one of the fastest growing
research areas in Computing Science.  The question whether DNA could
be used as the basis of a computing device has given rise to a new
topic of research.  Scientists all over the world are exploring the
possibility of building `biochips'.  Adleman's experiment to find a
Hamiltonian path in a graph using chemical reaction on DNA has started
this new exciting area of research.

It is clear that biochemists and Computer Scientists need to work
together to achieve practical results in this area.  It is of interest
to the Computer Scientist to find out what is possible and what is not
possible if and when such a `biochip' could be built.  It would also
be necessary to find out how easy or difficult it would be to solve
problems in such a system.  Since manipulation with DNA is
intrinsically parallel in nature, the algorithms developed should
exploit the massive parallelism available.  The complexity measures
will naturally be different from the ones for existing machines.  Also
there is a spurt of activity in Formal Language Theory because of this
development.  Starting from the work of Tom Head on Splicing systems
to model the recombinant behaviour of DNA sequences, Paun and others
have defined several variations of such systems as well as automata
like Watson-Crick automata.  Probing the generative capacity and
properties of such systems seems to be an interesting topic for
researchers in Formal Language Theory.

In this Workshop the concentration will be on the theoretical aspects
of DNA computing, like design of algorithms for problems using DNA and
studying their complexity.  We also take a closer look at various new
grammar and automata models that emerged due to the developments in
molecular computing.

Several prominent researchers will give talks at the workshop.  Among
them are Natasha Jonoska (USA), Kamala Krithivasan (India),
Georghe Paun (Romania), John Reif (USA), Yasubami Sakakibara (Japan),
Rani Siromoney (India), and K G Subramanian (India).


TARGET AUDIENCE

Researchers in the area of Theoretical Computer Science, Formal
Language Theory, Parallel and High Performance Computing, and
Biochemists exploring Molecular Computing.


PARTICIPATION

For logistic reasons, participation in the Workshop will be limited to
about sixty participants. Interested persons should write to the
address below before November 15, 1998.
 
The workshop is organised by Kamala Krithivasan.

                    SCHOOL ON FINITE MODEL THEORY                    
                        December 15--16, 1998                        
                            IMSc, Chennai                            


Finite model theory is concerned with the study of various logical
languages over classes of finite structures. This area has some
affinity with classical model theory but has developed a distinct
identity, both in terms of the questions considered and the techniques
used.  The questions it is concerned with are motivated by connections
with computation, and it has developed a variety of logics and new
techniques for studying their expressive power over finite structures.

Since its inception, finite model theory has had strong connections
with complexity theory and database theory. Recently, it has also
forged some connections with model checking, verification and dynamic
complexity, with its techniques contributing to these areas.

In this school, lectures will be given on core as well as on
application areas of finite model theory by the following speakers
(listed in alphabetical order).
  
  Anuj Dawar (Univ. of Wales Swansea)
  Martin Grohe (Univ. of Freiburg)
  Neil Immerman  (Univ. of Massachusetts at Amherst)
  Anil Seth (Inst. of Mathematical Sciences, Madras)
  Wolfgang Thomas (Univ. of Aachen)
  Moshe  Vardi (Rice University, Texas)
  Victor Vianu (University of California, San Diego)


TARGET AUDIENCE

Graduate students and researchers in the areas of Theoretical Computer
Science and Formal Logic.


PREREQUISITES

Some familiarity with logic at the level of first course and
familiarity with basic complexity classes.


PARTICIPATION

For logistic reasons, participation in the Workshop will be limited to
about sixty participants. Interested persons should write to the
address below before November 15, 1998.
 
The workshop is jointly organised by Anil Seth and Anuj Dawar.

TRAVEL AND MISCELLANEOUS INFORMATION

Chennai, formerly known as Madras, is served by several international
airlines, including Air India, British Airways, Lufthansa, Singapore
Airlines, Malaysian Airlines, Gulf Air. In addition, it has excellent
domestic air and train connections to Delhi and Mumbai (formerly
Bombay), which are served by virtually all international airlines.

Most international flights to/from India in December are booked months
in advance, since this is the prime tourist season. So you are advised
to start making your trip preparations at once. You are also advised
to apply early for a visa, since there can be a large delay in this
process. It is often simpler to apply for a *general tourist visa*
than to get a visa to attend the conference.

The climate in Chennai in December is usually quite pleasant, with day
temperatures ranging between 25 deg C and 30 deg C, and minimum
temperatures of 18 deg C to 20 deg C. Occasional rain showers are
common in December.


ACCOMMODATION

The FST&TCS Conference has not made any specific hotel bookings. A
list of conveniently located hotels, with tariff rates and telephone
and FAX numbers, is attached. You can download maps of Chennai and the
area around C.I.T. campus off the conference page. Contact the hotel
of your choice directly and finalise your accommodation
arrangements. Again, since this is the prime tourist season, you are
advised to finalise the hotel booking as early as possible.


SOCIAL EVENTS

A cultural programme will be organized at the Conference venue itself,
on the evening of 17th December. In addition, since the second half of
December is the classical music and dance season in Chennai, there
will be a surfeit of excellent performances all over town. Information
about these events will be available at the Conference registration
desk during the Conference.

There are several interesting sites near Chennai worth a visit.  If
there is sufficient interest, a full-day excursion to the temple town
of Kancheepuram and the temples and beaches of Mamallapuram can be
organized on 20th Deceember. Tentative rates for the excursion will be
made available shortly on the conference homepage.


ADDITIONAL INFORMATION

For more information, see the conference homepage, or send email to
"fsttcs98@imsc.ernet.in".  In particular, detailed instructions and
maps describing how to reach the conference venue will be posted on
the homepage.
