PAR'10 workshop is a venue for researchers working on new approaches to
cope with partial functions and terminating general (co)recursion in
theorem provers.

Theorem provers with inductive types provide a restricted programming
language together with a formal meta-theory for reasoning about the
language.  When propositions are represented as types and proofs as
programs, non-terminating proofs are disallowed for consistency and
decidability of type checking.  As a result, there is no trivial way to
represent partial functions, and termination is syntactically ensured by
imposing that the recursive calls must be made on structurally smaller
arguments. Similar issues exist for productivity of functions on
infinite objects where syntactic methods are used to ensure an infinite
flow of data. The workshop aims to address these issues and various
approaches for dealing with them.

We invite submissions on all aspects of partiality and termination of
general (co)recursive functions in a logical framework.

The topics of this workshop include but are not limited to:

* partial functions and functions over partial objects in theorem provers;

* specialised type systems for general (co)recursion;

* syntactical tests to guarantee termination of general recursive functions;

* syntactical tests to guarantee productivity of functions on infinite
objects;

* methods to ensure termination of special classes of recursion
definitions, eg nested recursion, simultaneous inductive-recursive data
types and functions;

* semantic approaches to termination and productivity, eg based on
domain theory and topology;

* categorical approaches to termination and productivity;

* algebra of programming with partial functions and general (co)recursion.

Description of software tools and case studies for dealing with the
issues in the scope of the workshop are welcome.


Submissions
-----------

The articles will be evaluated by the Program Committee for publication
in the proceedings of the workshop.  In accordance with FLoC'10
requirements, PAR'10 proceedings  will be published  in an electronic
collection available online and maintained by EasyChair. The USB memory
sticks with  accepted papers will be distributed during the workshop.

The  post-proceedings of PAR'10 will be published after the workshop as
a special issue of EPTCS. Details on how and when to produce the
post-workshop version of the articles will be communicated after the
workshop to the authors of the accepted papers.

The articles must contain original contributions, be clearly written,
and include appropriate reference to and comparison with related work.
Submissions should preferably not exceed 16 pages (excluding
bibliography). Submissions must be prepared in LaTeX using the EasyChair
latex package( http://www.easychair.org/easychair.zip).

The web-based system EasyChair will be used for submission
(<http://www.easychair.org/conferences/?conf=par10>).
