Title: Dimension Theory of hyperbolic IFS on the line

Abstract:
Let $I$ be a compact interval and $V\supset I$ be an open interval. Assume that the elements of the finite list $\mathcal{F}=\{f_1, \dots f_m\}$ of $C^1$ self mappings of $V$ also satisfies that $f_i(I) \subset I$ and there exists $0<c_1<c_2<1$ such that for all $1\leq i\leq m$ we have $c_1<|f'_i(x)|<c_2$, $x\in V$. Then we say that $\mathcal{F}$ is a hyperbolic IFS on $I$. All hyperbolic IFSs have an attractor $\Lambda$, which is the unique non-empty compact sset satisfying $\Lambda=\bigcup_{i=1}^{m} f_i(\Lambda)$. If the cylinders $\{f_i(\Lambda)\}_{i=1}^m$ are well separated (the so-called Open Set Condition (OSC) holds), then it is well known how to compute the Hausdorff dimension of $\Lambda$. If the OSC does not hold then we have only partial results. In my talk, I will review classical results and mention some new developments.

Title: Computability of Measures of Maximal Entropy on Coded Shift Spaces

Abstract:
Coded shifts are natural generalizations of sofic shifts, defined as the closure of all bi-infinite concatenations of words (generators) from a countable generating set 𝔾. In this talk, we present recent results on the computability of measures of maximal entropy (MMEs) for coded shift spaces.

Our first main result shows that if an MME assigns full measure to the set of concatenations, then it is unique, 𝔾-Bernoulli, and computable, provided that the Vere–Jones parameter of 𝔾 is computable. This yields computability of the MME for several well-known classes of shift spaces, including S-gap shifts, multiple gap shifts, and β-shifts. The same methods also establish the computability of the two ergodic MMEs of the Dyck shift.

We also examine the complementary case in which an MME assigns zero measure to the concatenation set. In this setting, MMEs are generally not unique. We show that even when the MME is unique and the Vere–Jones parameter is computable, the MME need not be computable in general. This is joint work with Tamara Kucherenko and Marco López.

Title: Spectral eigenvalue problem for self-similar spectral measures

Abstract:
A Borel probability measure $\mu$ on $\mathbb{R}$ is called a spectral measure if there exists a countable set $\Lambda \subset \mathbb{R}$ such that $\{ e_\lambda(x)=e^{2\pi \mathrm{i} \lambda x}: \lambda \in \Lambda \}$ forms an orthonormal basis in $L^2(\mu)$. The set $\Lambda$ is called a spectrum of $\mu$, and the pair $(\mu,\Lambda)$ is called a spectral pair. The study of spectral measures dates back to the famous Fuglede's spectral set conjecture. In 1998, Jorgensen and Pedersen discovered singular continuous self-similar spectral measures. An interesting phenomenon occurring in singular continuous spectral measures is the scaling spectrum: both the set $\Lambda$ and its scaling $t\Lambda$ for some $t>0$ are spectra. The scaling constant is called a spectral eigenvalue. In this talk, we will present recent results on the spectral eigenvalues for self-similar spectral measures generated by a Hadamard triple $(N,B,L)$. The first main result is the construction of a class spectral eigenvalues for these self-similar spectral measures. The second main result shows that when $\#B$ is small relative to $N$, for the canonical self-similar spectral pair $(\mu,\Lambda)$, there are infinitely many primes $p$ such that $(\mu,p\Lambda)$ is also a spectral pair. The proof is based on results concerning rational points in Cantor sets. Some of the talk will include joint with Derong Kong and Kun Li.

Title: The Baire Hierarchy, Multifractal Decomposition Sets and Π0γ-Completeness

Abstract:
This talk discusses the position of the so-called multifractal decomposition sets in the Baire hierarchy. In particular, we prove that multifractal decomposition sets are the building blocks from which all other Π0γ-sets can be constructed. More precisely, multifractal decomposition sets are Π0γ-complete.

As an application, we determine the position of the classical Eggleston–Besicovitch set in the Baire hierarchy.

Title: Transport alpha divergences

Abstract:
We derive a class of divergences measuring the difference between probability density functions on a one-dimensional sample space. This divergence is a one-parameter variation of the Itakura–Saito divergence between quantile density functions. We prove that the proposed divergence is a one-parameter variation of transport Kullback–Leibler divergence and Hessian distance of negative Boltzmann entropy with respect to the Wasserstein-2 metric. From Taylor expansions, we also formulate the 3-symmetric tensor in Wasserstein space, which is given by an iterative Gamma-three operator. The alpha-geodesic on Wasserstein space is also derived. From these properties, we name the proposed information measures transport alpha divergences. We provide several examples of transport alpha divergences for generative models in machine learning applications.

Sponsorship Opportunities

Individuals, departments, institutes, and organizations may also choose to sponsor an ISQGD activity, such as a Special Session, workshop, mini-course, or Distinguished Lecture. Sponsorship helps strengthen ISQGD’s technical capacity, expand programming, and keep its activities accessible to a broad international audience.

With the sponsor’s permission, sponsorship may be acknowledged on the event webpage, in announcements, and alongside archived materials. Any acknowledgment is purely informational and presented in a manner consistent with ISQGD’s academic mission and ethical standards.

Academic independence: Sponsorship does not imply endorsement, advertising, or influence over scholarly content, speaker selection, or program decisions. ISQGD retains full academic and organizational independence in all its activities.

We are sincerely grateful for every form of support—financial, organizational, and advisory—that helps ISQGD grow as a sustainable, professionally structured, and globally connected mathematical community.
