Linear logic for constructive mathematics
We show that numerous distinctive concepts of constructive mathematics arise
automatically from an interpretation of "linear higher-order logic" into
intuitionistic higher-order logic via a Chu construction. This includes
apartness relations, complemented subsets, anti-subgroups and anti-ideals,
strict and non-strict order pairs, cut-valued metrics, and apartness spaces. We
also explain the constructive bifurcation of classical concepts using the
choice between multiplicative and additive linear connectives. Linear logic
thus systematically "constructivizes" classical definitions and deals
automatically with the resulting bookkeeping, and could potentially be used
directly as a basis for constructive mathematics in place of intuitionistic
logic.Comment: 39 page
Kripke Models for Classical Logic
We introduce a notion of Kripke model for classical logic for which we
constructively prove soundness and cut-free completeness. We discuss the
novelty of the notion and its potential applications

Diphoton Production at Hadron Colliders and New Contact Interactions
We explore the capability of the Tevatron and LHC to place limits on the
possible existence of flavor-independent contact
interactions which can lead to an excess of diphoton events with large
invariant masses. Assuming no departure from the Standard Model is observed, we
show that the Tevatron will eventually be able to place a lower bound of
0.5-0.6 TeV on the scale associated with this new contact interaction. At the
LHC, scales as large as 3-6 TeV may be probed with suitable detector cuts and
an integrated luminosity of .Comment: LaTex, 12pages plus 5 figures(available on request), SLAC-PUB-657

Dualized Simple Type Theory
We propose a new bi-intuitionistic type theory called Dualized Type Theory
(DTT). It is a simple type theory with perfect intuitionistic duality, and
corresponds to a single-sided polarized sequent calculus. We prove DTT strongly
normalizing, and prove type preservation. DTT is based on a new propositional
bi-intuitionistic logic called Dualized Intuitionistic Logic (DIL) that builds
on Pinto and Uustalu's logic L. DIL is a simplification of L by removing
several admissible inference rules while maintaining consistency and
completeness. Furthermore, DIL is defined using a dualized syntax by labeling
formulas and logical connectives with polarities thus reducing the number of
inference rules needed to define the logic. We give a direct proof of
consistency, but prove completeness by reduction to L.Comment: 47 pages, 10 figure
