        Control Operators and their Semantics (COS'13) - Call for Papers

                       Satellite event of RDP'13

Modern programming languages provide sophisticated control mechanisms, commonly
referred to as control operators which are widely used to realize a variety of
applications. Since we cannot escape control features, it becomes a challenge
to provide them with sound reasoning principles. There is a very active research
on understanding, manipulating, representing, and reasoning about elaborated
non-local control structures, in particular in declarative programming languages
such as functional and logic languages. Ideas and results originating from this
research area have impact in many other areas of computer science, like distributed
and concurrent systems, proof theory, proof mining, web programming and linguistics.
For instance, the study of the logical foundations of control operators renewed the
study of the connections between proofs and programs via the so-called Curry-Howard
correspondence, providing new methods to extract the computational content of
classical proofs.

The focus of the workshop is on the interplay between syntax and semantics, namely
the central question of what a program means and how it does define the intended

This is a crucial issue especially in the case of control operators, since they are
as powerful as potentially obscure, and programs that use them are usually more error
prone than purely declarative ones.
The issue of a better understanding of control is also relevant for communicating
across different research areas and communities. More abstract views can be achieved
via several means, that include operational semantics of formal calculi, abstract
machines, algebraic specifications and rewriting, type assignment systems, denotational
semantics and game semantics, category theory and logic, to say the least.

Relevant topics include, but are not limited to:

- continuations and delimited continuations
- categorical models of continuations
- compositionality and modularity of control operators
- denotational semantics of control, event structures and causality
- operational semantics and abstract machines
- type systems for control operators
- game semantics of programming languages and of logical proofs
- usage of control operators in proof search and proof mining
- semantics of control operators in logic programming

Submission: authors of original works on the topic of the workshop
are invited to submit either a FULL PAPER of up to 20 pages, which
has to be unpublished nor submitted elsewhere, or an EXTENDED ABSTRACT
of up to 5 pages (to which previous restrictions do not apply)
for short presentation at the workshop.
Only accepted full papers will appear in the proceedings; the PC might
decide, on the ground of referees reports, that a full paper submission
is accepted as extended abstract instead.

Submission consists of a LaTex generated pdf file, prepared using EPTCS
macro package, available from: http://info.eptcs.org/
Authors of extended abstracts must add: "Extended Abstract" to the title.
