May 22 to May 22, 2026IMPA, Rio de Janeiro
6th Meeting on Women in Mathematics at IMPA
The Fridays Meeting on Women Mathematicians at IMPA – EMMI is organized by students from the Institute of Pure and Applied Mathematics to commemorate Women in Mathematics Day and promote a conversation about the reality of women in academic careers. In order to broaden the scope of the discussion, everyone is welcome and encouraged to attend.
In its sixth edition, the event will be held on May 22 and will seek to make explicit the participation of women and other underrepresented groups in mathematics, with lectures by invited researchers and very short presentations by people at the beginning of their careers. In addition, and in the style of the other editions, it will open a dialog between professors involved in minority issues in mathematics and the public.
In a hybrid format, the meeting will be broadcast simultaneously via the Zoom platform, making it possible to attend online or in person at the Impa auditorium. Registration is required to take part.
Women in Mathematics Day was created in 2018 and the date of May 12 was chosen in honor of the birth of Maryam Mirzakhani, the first mathematician to win the Fields Medal. Other events will be held in Brazil and around the world to celebrate this date. For more information, see: https://may12.womeninmaths.org/
Attention:
The event will be hybrid and only those registered will be able to access the virtual room. The access link will be sent by e-mail once registration has been completed.

Title: Support for the implementation of containerized workflows
Abstract: Deploying workflows faces challenges inherent to the specificities of execution environments and workflow characteristics. Although containers have revolutionized software deployment, they were designed to operate autonomously and in isolation, which contrasts with the interconnected nature of the components of a workflow. Defining the ideal composition of these containers is complex due to the number of alternatives and the variation in performance between different infrastructures. In addition, integrating the provenance of container and workflow data remains a gap in current solutions. This talk presents a study of container compositions for workflows in High Performance Environments (HPE), offering practical support for deployment. It also proposes a unified provenance model, based on representation patterns, for collecting and integrating execution traces. Results obtained with real workflows show that exploring different compositions, combined with the use of provenance data, is fundamental to the quality and reproducibility of containerized experiments.

Title: On Stationary Densities under Limited Variation Noise
Abstract: We study stationary measures of stochastic dynamical systems obtained by perturbing deterministic applications with i.i.d. additive noise whose distribution has a bounded variance. Our first objective is to establish the existence and regularity properties of the stationary densities, highlighting the smoothing effect induced by the noise and its interaction with the deterministic dynamics. Our second objective is to develop a rigorous framework for their numerical approximation, providing validated error bounds suitable for computer-assisted proofs via finite-point discretizations of transfer operators. We apply the theory to non-uniformly hyperbolic systems, including the Lorenz Contracting Attractor and the Hénon map, illustrating both the regularization phenomena and the feasibility of validated calculations. This is a joint work with Ricardo Bioni and Isaia Nisoli.
