A reappraisal of the Friedman-Kaldor debate in the light of the great recession [PDF]
SocioEconomic Challenges, 2022 This paper summarizes the arguments and counterarguments within the scientific discussion on the issue of the exogenous and endogenous money supply theories, developed by Milton Friedman and Nicholas Kaldor in the 1960s-1970s.

GENERICALLY FREE REPRESENTATIONS II: IRREDUCIBLE REPRESENTATIONS [PDF]
Transformation Groups, 2020 We determine which faithful irreducible representations $V$ of a simple linear algebraic group $G$ are generically free for Lie($G$), i.e., which $V$ have an open subset consisting of vectors whose stabilizer in Lie($G$) is zero. This relies on bounds on $\dim V$ obtained in prior work (part I), which reduce the problem to a finite number of ...

Algebras with representable representations [PDF]
Proceedings of the Edinburgh Mathematical Society, 2021 Just like group actions are represented by group automorphisms, Lie algebra actions are represented by derivations: up to isomorphism, a split extension of a Lie algebra $B$ by a Lie algebra~$X$ corresponds to a Lie algebra morphism $B\to \mathrm{Der}(X)$ from $B$ to the Lie algebra $\mathrm{Der}(X)$ of derivations on~$X$.

Development of Attention and Accuracy in Learning a Categorization Task
Frontiers in Psychology, 2021 Being able to categorize objects as similar or different is an essential skill. An important aspect of learning to categorize is learning to attend to relevant features (i.e., features that determine category membership) and ignore irrelevant features of

Cellists’ sound quality is shaped by their primary postural behavior
Scientific Reports, 2020 During the last 20 years, the role of musicians’ body movements has emerged as a central question in instrument practice: Why do musicians make so many postural movements, for instance, with their torsos and heads, while playing musical instruments?

Diffusion representations [PDF]
Applied and Computational Harmonic Analysis, 2018 Diffusion Maps framework is a kernel based method for manifold learning and data analysis that defines diffusion similarities by imposing a Markovian process on the given dataset. Analysis by this process uncovers the intrinsic geometric structures in the data.

IEEE Access, 2018 How do cellists' postural movements influence timbre quality during instrumental performance? If this question seems complex at a first glance partly due to specific motor synergies for each musician, some principles of postural organization are believed
