Abstract

While a non-concyclic rhombus can support a central configuration in the planar Newtonian four-body problem, such a configuration cannot serve as the base of a pyramidal central configuration in the spatial five-body problem. In this paper, we establish the existence of a new class of pyramidal central configurations in the spatial Newtonian six-body problem, characterized by a non-concyclic quadrilateral base. This geometric structure distinguishes the new configurations from the known pyramidal central configurations of the spatial five-body problem. We investigate several fundamental properties of these configurations and provide numerical examples illustrating the theoretical results in each case. Furthermore, we demonstrate that this new class of central configurations can be used to construct perverse solutions in three-dimensional space, revealing an additional connection between the geometry of central configurations and the dynamics of the Newtonian $N$-body problem.

Unstable entropy for Anosov diffeomorphisms on the 3-torus

For Anosov diffeomorphisms on the $3$-torus which are strongly partially hyperbolic with expanding center, we construct systems of strong unstable and center stable Margulis measures which are holonomy-invariant. This allows us to obtain a characterization of the measures of maximal unstable entropy in terms of their conditional measures along the strong unstable leaves. Moreover, we show that the Margulis systems identify with Pollicott-Ruelle (co)-resonant states for the action on 2-forms. This shows that the unstable topological entropy and a measure of maximal unstable entropy can be retrieved from the spectral approach.

Thermodynamic formalism and multifractal analysis of Birkhoff averages for non-uniformly expanding Rényi interval maps with countably many branches

In this paper, we study the multifractal spectrum of Birkhoff averages for non-uniformly expanding Rényi interval maps with countably many branches. Our main theorem substantially strengthens conditional variational formulas established by Jaerisch and Takahasi. Furthermore, our results enable a detailed analysis of Khinchin exponents and arithmetic means of backward continued fraction expansions in terms of the Hausdorff dimension. We also give a positive answer to the conjecture of Jaerisch and Takahasi. In addition, we develop the thermodynamic formalism for non-uniformly expanding Rényi interval maps with countably many branches.

On the intersection of Cantor sets and products of random matrices

Author's follow-up comment: The line of research pursued in this paper has been developed substantially further in my subsequent paper, Lyapunov exponents for random products of non-negative matrices (arXiv:2602.23317). I will therefore not pursue separate journal publication of the present paper. Original abstract: Kenyon and Peres (1991) showed that the Hausdorff dimension of intersections of randomly translated Cantor sets can be expressed in terms of the top Lyapunov exponent of a product of random matrices, and this exponent can be written as an integral with respect to stationary measures on the projective line. Although explicit computations are available when stationary measures are discrete, the continuous case has remained challenging. In this paper we introduce new combinatorial and analytic tools that allow us to compute the Lyapunov exponent, and hence the Hausdorff dimension, in a broad class of examples where stationary measures are continuous. As an application, we complete the dimension computation in the setting where a single digit is forbidden; for example, we determine the Hausdorff dimension of the intersection of the middle-seventh Cantor set with a random translate of itself.
