Title: Extraction of programs from proofs using postulated axioms
(joint work with Chi Ming Chuang)
Abstract:
In this talk we discuss how to extract programs from
proofs with postulated axioms in dependent type theory.
Since type theory has constructive logic, it is easy
to determine for every $\Pi_2$-statement a function
$f$ which determines the witness from the input.
However, in the presence of postulated axioms, this
function applied to an argument
doesn't reduce necessarily to constructor head normal
form, which means it doesn't produce a value.
In this talk we discuss conditions which guarantee
that the extracted function provide values in the presence of
postulated axioms, and give a proof.
This methodology will be applied to the extraction
of alogrithms for exact real number computations.
For this purpose the signed digit reals are introduced
as a coalgebraic data type, and it is shown that the signed digit
reals are closed under average, multiplication
and rational numbers. Proofs have been carried
out in the theorem prover Agda and the resulting
programs can be executed effectively in this
language.
Dear Sirs and Madams,
Regarding conflicts among religions and between religion and science, and
regarding the 1st World Congress on Logic and Religion
http://www.uni-log.org/logic-and-religion.html, I would inform you of the
paper entitled ``MATHEMATICAL THEOLOGY: A Proscience Concept of God with a
Mathematical Model'' http://homepage3.nifty.com/gomiken/english/mathpsy.htm.
I believe that it contributes to promoting harmony among religions and
reconciling religion and science toward omniscience.
Would you support it by forwarding this mail to your acquaintances who would
be interested?
With kind regards,
The original sender: Kensaku Gomi, a retired professor of the Graduate
School of Mathematical Sciences, University of Tokyo.
Third Workshop on Natural Language and Computer Science
NLCS '15
July 5, 2015
Kyoto, Japan
http://www.indiana.edu/~iulg/nlcs.html
A workshop affiliated with 42nd International Colloquium on Automata, Languages and Programming (ICALP 2015) and 30th Annual ACM/IEEE Symposium on Logic in Computer Science (LICS 2015)
Endorsed by the Association for Computational Linguistics Special Interest Group on Computational Semantics
Paper submission deadline: April 2, 2015
AIMS AND SCOPE
Formal tools coming from logic and category theory are important in both natural language semantics and in computational semantics. Moreover, work on these tools borrows heavily from all areas of theoretical computer science. In the other direction, applications having to do with natural language has inspired developments on the formal side. The workshop invites papers on both topics. Specific topics includes, but are not limited to:
• logic for semantics of lexical items, sentences, discourse and dialog
• continuations in natural language semantics
• formal tools in textual inference, such as logics for natural language inference
• applications of category theory in semantics
• linear logic in semantics
• formal approaches to unifying data-driven and declarative approaches to semantics

Subject: UNILOG'2015 in Istanbul and 10th PLS in Samos Island
Hope to see you at the 5th UNILOG -
World Congress and School on Universal Logic to happen in Istanbul, June 20-30, 2015
http://www.uni-log.org/enter-istanbul
As indicated in our website:
The event is organized in combination with the 10th Panhellenic Logic Symposium that will happen June 11-15, 2015 in Samos Island, where Pythagoras was born.
https://samosweb.aegean.gr/pls10/
A travel by bus from the nearby port of Kusadasi in Turkey up to Istanbul will be organized with stops on famous historical sites: Ephesus, Troy, etc. Special arrangements will exist for participants who wish to attend both conferences.
I am sending you attached the posters for UNILOG'2015 and the related contest "The Future of Logic".
I would be glad if you can print them (colour A3) and post them at your university /institute
or if you prefer I can send them to you by post (then send me your exact mailing address)
I wish you a happy new year 2015

PAPER SUBMISSION
Contributions are invited on all pertinent subjects, with particular interest in cross-disciplinary topics. Typical but not exclusive areas of interest are: foundations of computing and programming; novel computation models and paradigms; broad notions of proof and belief; proof mining, type theory, effective learnability; formal methods in software and hardware development; logical approach to natural language and reasoning; logics of programs, actions and resources; foundational aspects of information organization, search, flow, sharing, and protection; foundations of mathematics; philosophical logic. Proposed contributions should be in English, and consist of a scholarly exposition accessible to the non-specialist, including motivation, background, and comparison with related works. They must not exceed 10 pages (in font 10 or higher), with up to 5 additional pages for references and technical appendices. The paper's main results must not be published or submitted for publication in refereed venues, including journals and other scientific meetings. It is expected that each accepted paper be presented at the meeting by one of its authors. Papers must be submitted electronically at the WoLLIC 2015 EasyChair website. (Please go to http://wollic.org/wollic2015/instructions.html <http://wollic.org/wollic2015/instructions.html> for instructions.)
