Please note the following in particular.
- We are asking all attendees to register for the meeting.
- There is a block of hotel rooms held for us until April 3 at a special rate at Ivy Court Inn on the edge of Notre Dame's campus. The weekend seems to be a little busy, so it's probably good to take advantage of these rooms.
- We have some funding available for participants with the usual preference for younger mathematicians. To receive full consideration, please register and request funding by Monday, March 9.
- The meeting will include a poster session. Again, you can indicate interest in presenting when you register.

The conference entitled "Rice Geometry and Dynamics" will be hosted April 10-12, 2026 at Rice University in Houston, Texas. The conference aims to bridge the gap between differential geometry and dynamics, exploring themes related to special submanifolds (e.g. minimal, totally geodesic) and negative curvature. Talks will begin Friday afternoon and end Sunday late morning with the following speakers:
Lewis Bowen (University of Texas, Austin)
Yaiza Canzani (University of North Carolina, Chapel Hill)
Riccardo Caniato (California Institute of Technology)
Ben Dozier (Cornell University)

This conference is generously supported by Rice University and its Creative Ventures Fund: Conference and Workshop Development, which will provide lodging funding for many participants. We only expect to be able to give travel funding in exceptional cases. Priority will be given to early career participants.

The 2026 Spring Dynamics Workshop at the University of Maryland will take place from April 9 to April 12 2026. This is the latest of a long-running series of semi-annual workshops run by the dynamics groups at Penn State University and the University of Maryland.
Special events include:
1) The Chernov Memorial Lectures by Dmitry Dolgopyat
2) The 15th Michael Brin Prize in dynamical systems (April 10th)

Advances in Dynamics Seminar 8AM-11AM (US eastern time)
Featured Speakers:
8am - 9am: Raphaël Krikorian (Ecole Polytechnique)
Title: Exotic rotation domains and Herman rings for quadratic Hénon maps
Abstract: Quadratic Hénon maps are polynomial automorphism of $\mathbb{C}^2$ of the form $h:(x,y)\mapsto (\lambda^{1/2}(x^2+c)-\lambda y,x)$.
They have constant Jacobian equal to $\lambda$ and they admit two fixed points. If $\lambda$ is on the unit circle (one says the
map $h$ is conservative) these fixed points can be elliptic or hyperbolic. In the elliptic case, a simple application of Siegel Theorem
shows (under a Diophantine assumption) that $h$ admits many quasi-periodic orbits with two frequencies in the neighborhood of its fixed
points. Surprisingly, in some hyperbolic cases, S. Ushiki observed some years ago what seems to be quasi-periodic orbits though no
Siegel disks exist. I will explain why this is the case. This theoretical framework also predicts and mathematically proves, in the
dissipative case ($\lambda$ of module less than 1), the existence of (attractive) Herman rings. These Herman rings, which were not
observed before, can be produced in numerical experiments.
9am - 10am: Bertrand Deroin (CNRS - CYU)
Title: Towards a Structural Stability Theory for Holomorphic Foliations on Algebraic Complex Surfaces
Abstract: I'll review work done in collaboration with Aurélien Alvarez, aiming at developing a theory of structural stability for
holomorphic foliations on compact complex surfaces. Important new examples are the Jouanolou foliations of the complex projective
plane, and the fundamental properties they satisfy allow us to define a more general family of foliations on arbitrary algebraic
surfaces, which we call Jouanolou-type foliations. I will present these conditions, as well as some of their properties, and, time
permitting, I will state a number of conjectures.
10am - 11am: Giovanni Forni (CYU - University of Maryland)
Title: On the dynamics of billiards in polygons
Abstract: In this talk we will survey several results on the dynamics of billiards in polygons. These include results on their ergodic
theory (weak mixing), KAM-type results on stability of invariant surfaces of rational billiards under perturbations and existence of
periodic orbits. Part of the work is in collaboration with F. Arana Herrera and J. Chaika.

2025 DKO Workshop and Summer School on Transcendental Thurston Theory*, will take place at the University of Manchester from August 26-29, 2025. The workshop is intended to bring together researchers into Thurston theory and those from transcendental dynamics, as well as PhD students in holomorphic dynamics. There will be a series of introductory talks to introduce and motivate the central conjectures of Transcendental Thurston Theory, as well as research talks describing the current state of the art. The workshop is kindly funded by the Dame Kathleen Olleranshaw Trust at the University of Manchester.
