Deformation theory of symplectic and orthogonal sheaves
Por Emílio Franco (IST).
Abstract: While it is well known that the moduli space of G-bundles over a smooth projective curve is compact, it is not the case for an arbitrary base variety. This motivated the definition of G-sheaves by Gomez and Sols who proved that their moduli space is a compactification of the moduli space of G-bundles. In this talk I will study the deformation and obstruction theory of these objects when G is either the symplectic or the orthogonal group.
Hugo Messias, duplamente premiado
O Prémio Breakthrough em Física Fundamental 2020, um dos mais prestigiantes em Física, foi atribuído ao projeto Event Horizon Telescope (EHT) e a cada um dos 347 membros, incluindo o português Hugo Messias, antigo aluno da Ciências ULisboa e atualmente investigador do Instituto de Astrofísica e Ciências do Espaço. Hugo Messias foi ainda galardoado este ano com o prémio GQ Men of the Year, na categoria ciência.
About some energy functionals which penalize oscillations in oblique directions

A two-phase two fluxes degenerate Cahn-Hilliard model as constrained Wasserstein gradient flow
Por Clément Cancès (Inria Lille - Nord Europe).
Abstract: We present an original model for immiscible two-phase mixtures. This model can be interpreted as the generalised gradient flow of the same energy as for the classical degenerate Canh-Hilliard model, but for a different geometry. Our model is shown to dissipate faster. Existence of weak solutions is established based on the convergence of a JKO semi discretization (joint work with Flore Nabet and Daniel Matthes).
Black Swan Physics: Unveiling Hidden Predictability Beyond Recurrence Collapse in Complex Coevolutionary Systems
Speaker: Rui A. P. Perdigão (cE3c - Faculdade de Ciências da Universidade de Lisboa).
Multi-messenger Astrophysics for observing the high-energy universe
Por Teresa Montaruli (Univ. Geneve / Chair of APPEC).
I will describe how photons can be complemented for the observation of the non-thermal universe by neutrinos and gravitational way.
IceCube, with its cubic-kilometric volume deep in the ice of the South Pole, is now monitoring the sky looking for neutrino flares of compact objects like pulsars and black holes.
I will present its recent results on cosmic exploration and on fundamental physics such as neutrino oscillations.

First results of the SNO+ experiment
Por Valentina Lozza (LIP & FCUL).
SNO+ is a large multi-purpose liquid scintillator based experiment, with the main physics goal of searching for the neutrinoless double-beta decay of 130Te.
The first of the three SNO+ phases has started in May 2017, with the detector filled with ultra-pure water. The deep underground location (6000 m.w.e.) and the low background levels, allowed new physics searches and the 8B solar neutrino flux measurement in the 5-10 MeV energy range.
