We experiment a method for representing a concurrent object calculus in the Calculus of Inductive Constructions. Terms are rst deened in de Bruijn style, then names are reintroduced in binders. The terms of the calculus are formalized in the mechanized logic by suitable subsets of the de Bruijn terms; namely those whose de Bruijn indices are relayed beyond the scene. The-equivalence relation is...

Takhtajan has recently studied the consistency conditions for Nambu brackets, and suggested that they have to be skew-symmetric, and satisfy Leibnitz rule and the Fundamental Identity (FI, it is a generalization of the Jacobi identity). If the n-th order Nambu brackets in dimension N is written as {f1, . . . , fn} = ηi1...in∂i1f1 · · · ∂infn (where the iα summations range over 1 . . . N), the F...

Large-N multi-matrix loop equations are formulated as quadratic difference equations in concatenation of gluon correlations. Though non-linear, they involve highest rank correlations linearly. They are underdetermined in many cases. Additional linear equations for gluon correlations, associated to symmetries of action and measure are found. Loop equations aren’t differential equations as they i...

In this paper we develop a rigorous foundation for the study of integration and measures on the space G (V ) of all graphs defined on a countable labelled vertex set V . We first study several interrelated σ-algebras and a large family of probability measures on graph space. We then focus on a “dyadic” Hamming distance function ‖·‖ψ,2, which was very useful in the study of differentiation on G ...

The single-layer perovskite cobaltates have attracted enormous attention due to the recent observation of hour-glass shaped magnetic excitation spectra which resemble the ones of the famous high-temperature superconducting cuprates. Here, we present an overview of our most recent studies of the spin and charge correlations in floating-zone grown cobaltate single crystals. We find that frustrati...

It has been found that the cosmic-ray particles which occur in showers of small angular divergence are much more penetrating than those of the usual type of shower. The particles in such "hard showers" are clearly not electrons and are interpreted as medium and low energy mesotrons. The second maximum of the Rossi curve, which is accentuated for small-angle shower arrangements, can be accounted...

We prove that a dialgebra (coming from K-theory) can be embedded into an associative conformal algebra (coming from conformal field theory). This shows that these notions are related in the same way as ordinary associative algebras related to Lie algebras. The notion of a dialgebra originally appear in K-theory as an analogue of the universal associative envelope for Leibnitz algebras [L1]. On ...
