Dear all, we are pleased to announce the following workshops in Bologna:

-----------------------------------------

1) Manifolds and groups in Bologna (Workshop funded by GNSAGA (INdAM))

Date: Wednesday, Mar 22, 2023 -- Thursday, Mar 23, 2023

Place: Bologna - Dipartimento di Matematica

The aim of this workshop is to bring together young researchers working in low-dimensional topology and geometric group theory in a broad sense. The event consists in main lectures and shorter talks in order to give the opportunity to young researchers to present their own research. The workshop is hosted by the University of Bologna and it is sponsored by the GNSAGA (INdAM).

After the workshop, the University of Bologna will host the Attività presso l’Unità di Ricerca INdAM “Non-positive curvature in manifolds and groups” (March 24, 2023), sponsored by INdAM. This one-day event will consist in four main lectures given by international speakers.

Main speakers: Gianluca Faraco (Università di Milano Bicocca) Francesco Fournier Facio (ETH Zürich) Alessio Savini (Univeristé de Genève)

Junior speakers: Federica Bertolotti (SNS Pisa) Viola Giovannini (Université du Luxembourg) Giovanni Italiano (SNS Pisa) Bianca Marchionna (Università di Milano Bicocca) Matteo Migliorini (SNS Pisa) Francesco Milizia (SNS Pisa) Diego Santoro (SNS Pisa) Matteo Tarocchi (Università di Pavia) Enrico Trebeschi (Università di Pavia)

Organizers Ludovico Battista, Stefano Francaviglia, Marco Moraschini, Stefano Riolo (Alma Mater Studiorum Università di Bologna) and Filippo Sarti (Università di Torino)

2) Non-positive curvature in manifolds and groups (Attività presso l'Unità di Ricerca INdAM di Bologna)

Date: Friday, Mar 24, 2023

Place: Bologna - Dipartimento di Matematica

The aim of this event is to bring together researchers working in geometric topology and geometric group theory, mainly focusing on non-positive curvature phenomena. It is hosted by the University of Bologna and sponsored by INdAM.

Before this event, the University of Bologna will host the workshop “Manifolds and groups in Bologna” (March 22-23, 2023, sponsored by GNSAGA — INdAM ), on the same research themes, particularly addressed to the participation and interaction of young researchers.

Speakers: Caterina Campagnolo (UAM - Universidad Autónoma de Madrid) Irene Pasquinelli (University of Bristol) Andrea Seppi (Université Grenoble Alpes) Leone Slavich (Università di Pavia)

Organizers Pierluigi Contucci (direttore dell'UdR INdAM di Bologna), Ludovico Battista, Stefano Francaviglia, Marco Moraschini, Stefano Riolo (Alma Mater Studiorum Università di Bologna) e Filippo Sarti (Università di Torino)
