Simulation in the call-by-need lambda-calculus with letrec [PDF]

open access: yes, 2010
This paper shows the equivalence of applicative similarity and contextual approximation, and hence also of bisimilarity and contextual equivalence, in the deterministic call-by-need lambda calculus with letrec.

On embedding Lambek calculus into commutative categorial grammars [PDF]

open access: yesJournal of Logic and Computation, 2021
AbstractWe consider tensor grammars, which are an example of ‘commutative’ grammars, based on the classical (rather than intuitionistic) linear logic. They can be seen as a surface representation of abstract categorial grammars (ACG) in the sense that derivations of ACG translate to derivations of tensor grammars and this translation is isomorphic on ...

Generating q-Commutator Identities and the q-BCH Formula

open access: yesAdvances in Mathematical Physics, 2016
Motivated by the physical applications of q-calculus and of q-deformations, the aim of this paper is twofold. Firstly, we prove the q-deformed analogue of the celebrated theorem by Baker, Campbell, and Hausdorff for the product of two exponentials.

Provably correct Java implementations of Spi Calculus security protocols specifications [PDF]

open access: yes, 2010
Spi Calculus is an untyped high level modeling language for security protocols, used for formal protocols specification and verification. In this paper, a type system for the Spi Calculus and a translation function are formally defined, in order to ...

Model checking probabilistic and stochastic extensions of the pi-calculus [PDF]

open access: yes, 2009
We present an implementation of model checking for probabilistic and stochastic extensions of the pi-calculus, a process algebra which supports modelling of concurrency and mobility.

Relative unitary commutator calculus, and applications [PDF]

open access: yes, 2020
. This note revisits localisation and patching method in the setting of generalised unitary groups. Introducing certain subgroups of relative elementary unitary groups, we develop relative versions of the conjugation calculus and the commutator calculus ...

Quantum stochastic calculus with maximal operator domains. [PDF]

open access: yes, 2004
Quantum stochastic calculus is extended in a new formulation in which its stochastic integrals achieve their natural and maximal domains. Operator adaptedness, conditional expectations and stochastic integrals are all defined simply in terms of the ...

Noncommutative integration calculus [PDF]

open access: yesJournal of Mathematical Physics, 1995
A noncommutative integration calculus arising in the mathematical description of Schwinger terms of fermion–Yang–Mills systems is discussed. The differential complexes of forms u0[ε,u1]...[ε,un] with ε a grading operator on a Hilbert space ℋ and ui bounded operators on ℋ which naturally contains the compactly supported de Rham forms on Rd (i.e., ε is ...

!COMMUTANT LIFTING, TENSOR ALGEBRAS, AND FUNCTIONAL CALCULUS [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 2001
AbstractA non-commutative multivariable analogue of Parrott’s generalization of the Sz.-Nagy–Foia\c{s} commutant lifting theorem is obtained. This yields Tomita-type commutant results and interpolation theorems (e.g. Sarason, Nevanlinna–Pick, Carathéodory) for $F_n^\infty\,\bar{\otimes}\,\M$, the weakly-closed algebra generated by the spatial tensor ...
