        ************************************************************

The 1996 International Conference on Theorem Proving in Higher Order Logics
will be held on 27-30 August 1996 (Tuesday to Friday) in Turku (Abo in Swedish)
in the South-west corner of Finland. Two tutorials are also included, starting
after midday on Monday 26th August.

The conference will be a venue for presentations on the following topics, among
others: advances in interactive theorem proving, proof automation and decision
procedures, applications of mechanized theorem proving, comparison between
different theorem proving approaches, exploiting external tools within theorem
provers and incorporating theorem provers into larger systems.

Previous conferences have been at Cambridge (UK), Aarhus, Davis, Leuven,
Vancouver, Malta and Salt Lake City. This conference is being organized by the
Turku Centre for Computer Science (TUCS) and Abo Akademi University.

  ****************************************************************************
  * The third Workshop on Designing Correct Circuits (DCC) will be held from *
  * Monday 2 September to Wednesday 4 September 1996 at Bastad in Southern   *
  * Sweden. This is an excellent opportunity for researchers from outside    *
  * Europe to attend both conferences.                                       *

  ============================================================================

                                REGISTRATION

The fee for early registration, on or before Friday 21 June is FIM200. There
are separate fees for accommodation and meals. If, as we expect, you are
staying at the conference venue, Turun Kristillinen Opisto, the cost is FIM200
per person (single) or FIM150 per person (shared), per night. If you prefer to
stay at a central hotel, the corresponding costs will be approximately FIM270
and FIM150. Meals, conference banquet and refreshments for the whole
conference cost an additional FIM876 per person, or FIM705 for guests not
requiring refreshments during the breaks. A more detailed breakdown of the
costs is available on the Web at:

  http://www.abo.fi/~jharriso/cost.html

After Friday 21 June, the registration fee rises to FIM250, and after the end
of July, we will be unable to guarantee accommodation at the same price and
standard. You can register via the Web; see:

  http://www.abo.fi/~jharriso/webform.html

Alternatively, fill in the following form, and either:

 * Email it to "orgcom@abo.fi"

 * Fax it to any member of the organizing committee on +358 21 265-4732

 * Send it by mail to the organizing committee (see the address above).

By registering for TPHOLs'96 you are agreeing to pay the applicable
registration fee even if you subsequently fail attend the conference. If you
are unable to attend the conference then the organizing committee may waive the
fee if you inform us of your change of plans in a timely manner. However, if
you just fail to show up, we are going to want our money.
