Dear Everyone,

As requested by the participants of the RTA-TLCA conference
in Vienna 2014, the united Steering Committees of Rewriting
Techniques and Applications (RTA) and Typed Lambda Calculi and
Applications (TLCA) have prepared the attached proposal to replace
our existing two conferences by a new one of a broader scope.

As we embark on this exciting journey, we invite all members of the
computer science community to provide comments, remarks, and
suggestions for the new conference. All input will be passed on to the
steering committee of the new conference after its constitutional
general meeting on July 1st, 2015.

for the unanimous steering committees of RTA and TLCA.


                               It is our thesis that formal elegance is
                            a prerequisite to efficient implementation.
                                                      -- Gérard Huet[4]

We, the communities behind the RTA[1] and TLCA[2] conferences, believe
that our field has evolved and developed richer connections with many
both practical and theoretical aspects of computer science and logic
research since the inception of RTA in 1983 and TLCA in 1993. In
particular, the scope of the two original conferences widened to
include a significant overlap, and in fact the conferences have
already collaborated by having most of our meetings since 2003 as the
joint RDP[3] conference.

We have therefore decided to propose a new conference,

         Formal Structures for Computation and Deduction (FSCD)

which not only combines our scope but further extends it to cover all
the inter-related formal areas that researchers in formal structures
for computation and deduction engage in.

The name of the new conference comes from an unpublished but important
book by Gérard Huet[4] that was a strong influence on many researchers
in our area. We are grateful to Gérard for allowing us to reuse the

The extended scope of the conference will include all research related
to formal structures for computation and deduction, in particular all
areas/categories included in the attached non-exhaustive list of

We look very much forward to serve the scientific community with this
new conference, which inherits as well as updates and modernizes the
scope of the conferences it replaces.


FSCD initial non-exhaustive list of topics (intended to extend the
current RTA and TLCA scope, and expected to evolve over time):
