چکیده
Boolean, free and monotone cumulants as well relations among them, have proven to be important in the study of non-commutative probability theory. Quite notably, Boolean were successfully used infinite divisibility via Bercovici--Pata bijection. On other hand, recent years concept infinitesimal has been developed, together with notion which can useful context combinatorial questions. In this paper, we show that known free, still hold framework. Our approach is based on use Grassmann algebra. Formulas involving obtained by applying a formal derivation formulas. The between various types turn out captured shuffle algebra moment-cumulant In formulation, (free, monotone) are represented elements Lie characters over particular Hopf The latter consists graded connected double tensor defined space neither commutative nor cocommutative. note it shown how naturally extends space. basic step replacing base field target linear maps field. We also consider analog map.

Relations between Non-Commutative and Commutative Spacetime1
Spacetime non-commutativity appears in string theory. In this paper, the non-commutativity in string theory is reviewed. At first we review that a Dp-brane is equivalent to a configuration of infinitely many D(p− 2)-branes. If we consider the worldvolume as that of the Dp-brane, coordinates of the Dp-brane is commutative. On the other hand if we deal with the worldvolume as that of the D(p− 2)-...
متن کاملRelations between Cumulants in Noncommutative Probability
We express classical, free, Boolean and monotone cumulants in terms of each other, using combinatorics of heaps, pyramids, Tutte polynomials and permutations. We completely determine the coefficients of these formulas with the exception of the formula for classical cumulants in terms of monotone cumulants whose coefficients are only partially computed.
متن کاملMaps between Non-commutative Spaces
Let J be a graded ideal in a not necessarily commutative graded k-algebra A = A0⊕A1⊕· · · in which dimk Ai <∞ for all i. We show that the map A→ A/J induces a closed immersion i : Projnc A/J → Projnc A between the non-commutative projective spaces with homogeneous coordinate rings A and A/J . We also examine two other kinds of maps between non-commutative spaces. First, a homomorphism φ : A → B...
متن کاملCumulants as non Gaussian qualifiers
We discuss the requirements of good statistics for quantifying nonGaussianity in the Cosmic Microwave Background. The importance of rotational invariance and statistical independence is stressed, but we show that these are sometimes incompatible. It is shown that the first of these requirements prefers a real space (or wavelet) formulation, whereas the latter favours quantities defined in Fouri...
متن کاملNon-commutative Gröbner Bases for Commutative Algebras
An ideal I in the free associative algebra k〈X1, . . . ,Xn〉 over a field k is shown to have a finite Gröbner basis if the algebra defined by I is commutative; in characteristic 0 and generic coordinates the Gröbner basis may even be constructed by lifting a commutative Gröbner basis and adding commutators.
