Repeated differentiation and free unitary Poisson process

Z Kabluchko - arXiv preprint arXiv:2112.14729, 2021 - arxiv.org
We investigate the hydrodynamic behavior of zeroes of trigonometric polynomials under
repeated differentiation. We show that if the zeroes of a real-rooted, degree $ d …

Lee-Yang zeroes of the Curie-Weiss ferromagnet, unitary Hermite polynomials, and the backward heat flow

Z Kabluchko - arXiv preprint arXiv:2203.05533, 2022 - arxiv.org
The backward heat flow on the real line started from the initial condition $ z^ n $ results in
the classical $ n $-th Hermite polynomial whose zeroes are distributed according to the …

Combinatorial theory of permutation-invariant random matrices II: cumulants, freeness and Levy processes

F Gabriel - arXiv preprint arXiv:1507.02465, 2015 - arxiv.org
The $\mathcal {A} $-tracial algebras are algebras endowed with multi-linear forms,
compatible with the product, and indexed by partitions. Using the notion of $\mathcal {A} …

New combinatorial identity for the set of partitions and limit theorems in finite free probability theory

O Arizmendi, K Fujie, Y Ueda - … Mathematics Research Notices, 2024 - academic.oup.com
We provide a refined combinatorial identity for the set of partitions of, which plays an
important role in investigating several limit theorems related to finite free convolutions …

[HTML][HTML] The generalized master fields

G Cébron, A Dahlqvist, F Gabriel - Journal of Geometry and Physics, 2017 - Elsevier
The master field is the large N limit of the Yang–Mills measure on the Euclidean plane. It can
be viewed as a non-commutative process indexed by loops on the plane. We construct and …

[HTML][HTML] Haar states and Lévy processes on the unitary dual group

G Cébron, M Ulrich - Journal of Functional Analysis, 2016 - Elsevier
We study states on the universal noncommutative⁎-algebra generated by the coefficients of
a unitary matrix, or equivalently states on the unitary dual group. Its structure of dual group in …

The exponential map in non-commutative probability

M Anshelevich, O Arizmendi - … Mathematics Research Notices, 2017 - academic.oup.com
The wrapping transformation is a homomorphism from the semigroup of probability
measures on the real line, with the convolution operation, to the semigroup of probability …

Formal groups, Witt vectors and free probability

R Friedrich, J McKay - arXiv preprint arXiv:1204.6522, 2012 - arxiv.org
We establish a link between free probability theory and Witt vectors, via the theory of formal
groups. We derive an exponential isomorphism which expresses Voiculescu's free …

Additive processes on the unit circle and Loewner chains

T Hasebe, I Hotta - International Mathematics Research Notices, 2022 - academic.oup.com
This paper defines the notion of generators for a class of decreasing radial Loewner chains
that are only continuous with respect to time. For this purpose,“Loewner's integral equation” …

Limit theorems for free Lévy processes

O Arizmendi, T Hasebe - 2018 - projecteuclid.org
We consider different limit theorems for additive and multiplicative free Lévy processes. The
main results are concerned with positive and unitary multiplicative free Lévy processes at …
