Tropicalising hypergeometric -functions

Marvin Anas Hahn, Brian O'Callaghan, Jonas Wahl

Weighted Hurwitz numbers arise as coefficients in the power sum expansion of deformed hypergeometric --functions. They specialise to essentially all known cases of Hurwitz numbe…

Conditional Independence Testing with Heteroskedastic Data and Applications to Causal Discovery

Wiebke Günther, Urmi Ninad, jonas Wahl +1

Conditional independence (CI) testing is frequently used in data analysis and machine learning for various scientific fields and it forms the basis of constraint-based causal disco…

Foundations of Causal Discovery on Groups of Variables

Jonas Wahl, Urmi Ninad, Jakob Runge

Discovering causal relationships from observational data is a challenging task that relies on assumptions connecting statistical quantities to graphical or algebraic causal models.…

Causal Inference on Process Graphs, Part I: The Structural Equation Process Representation

Nicolas-Domenic Reiter, Andreas Gerhardus, Jonas Wahl +1

When dealing with time series data, causal inference methods often employ structural vector autoregressive (SVAR) processes to model time-evolving random systems. In this work, we…

Vector causal inference between two groups of variables

Jonas Wahl, Urmi Ninad, Jakob Runge

Methods to identify cause-effect relationships currently mostly assume the variables to be scalar random variables. However, in many fields the objects of interest are vectors or g…

Traces on diagram algebras II: Centralizer algebras of easy groups and new variations of the Young graph

Jonas Wahl

In continuation of our recent work arXiv:2006.07312, we classify the extremal traces on infinite diagram algebras that appear in the context of Schur-Weyl duality for Banica and Sp…

Traces On Diagram Algebras I: Free Partition Quantum Groups, Random Lattice Paths And Random Walks On Trees

Jonas Wahl

We classify extremal traces on the seven direct limit algebras of noncrossing partitions arising from the classification of free partition quantum groups of Banica-Speicher (arXiv:…

The Fourier algebra of a rigid -tensor category

Yuki Arano, Tim de Laat, Jonas Wahl

Completely positive and completely bounded mutlipliers on rigid -tensor categories were introduced by Popa and Vaes. Using these notions, we define and study the Fourier-…

Bernoulli actions of type III_1 and L^2-cohomology

Stefaan Vaes, Jonas Wahl

We conjecture that a countable group admits a nonsingular Bernoulli action of type III if and only if the first -cohomology of is nonzero. We prove this conjecture…

Free wreath product quantum groups and standard invariants of subfactors

Pierre Tarrago, Jonas Wahl

By a construction of Vaughan Jones, the bipartite graph associated with the natural inclusion of inside a finite-dimensional -algebra gives rise to a pl…

Howe-Moore type theorems for quantum groups and rigid C*-tensor categories

Yuki Arano, Tim de Laat, Jonas Wahl

We formulate and study Howe-Moore type properties in the setting of quantum groups and in the setting of rigid -tensor categories. We say that a rigid -tensor c…

A note on reduced and von Neumann algebraic free wreath products

Jonas Wahl

In this paper, we study operator algebraic properties of the reduced and von Neumann algebraic versions of the free wreath products , where is a…
