Asymptotic stability for the gradient flow of some nonlocal energies | 14h00-15h00
Nicola Fusco (Università di Napoli "Federico II")

I will start by discussing some recent results on the asymptotic stability of the $H^{-1}$-gradient flow of the perimeter, the so called surface diffusion. Then I will consider the $H^{-1}$-gradient flow of some energy functionals given by the area of an interface plus a non local volume term.

This is a joint work with E. Acerbi, V. Julin and M. Morini


Nonlocality features of the area functional and the Plateau problem | 15h00-16h00
Riccardo Scala (Università degli Studi di Siena)

We briefly discuss the definition of relaxation of the area functional. The relaxed area functional, denoted by $A$, extends the classical area functional, which, for any "regular" map $v:U\subset \mathbb{R}^n\rightarrow \mathbb{R}^N$ evaluates the $n$-dimensional area of its graph over $U$. The problem of determining the domain and the expression of $A$ is open in codimension greater than 1. Specifically, this relaxed functional turns out to be nonlocal and cannot be expressed by an integral formula. We discuss how it is related to classical and nonclassical versions of the Plateau problem. As a main example, we try to understand what is the relaxed graph of the function $x/|x|$, a question that surprisingly remained open for decades.

The Lisbon Webinar in Analysis in Differential Equations is a joint iniciative of CAMGSD, CMAFcIO and GFM, three research centers of the University of Lisbon. It is aimed at filling the absence of face-to-face seminars and wishes to be a meeting point of mathematicians working in the field.

14h00-16h00

Seminário do Laboratório de Instrumentação e Física Experimental de Partículas, por Philip Patrick Allport (University of Birmingham).

Seminário de Pós-graduação (Doutoramento em Biologia - Especialidade de Biologia Evolutiva), por Marta Maria Alves Antunes.

This talk will cover new methodologies of scientific visualization in high-performance computing systems specially designed for large scale scientific visualization that provide greater level of accuracy and detail.

This is the 11th edition of the Combinatorics Days, to be held online, Zoom platform, on the 21st and the 22nd of January.

Como é de conhecimento geral, assistimos atualmente a um rápido desenvolvimento nas formas de acesso à informação e publicação científica. O objetivo da jornada é fazer o ponto da situação na área da Matemática e discutir as perspetivas futuras.

The course SoilEco aims at introducing attendants to an updated state of the art of diversity of the soil biota and the functional roles played by soil organisms in key ecological processes.

A ULisboa promove o Dia Aberto M23, um evento que pretende aproximar o público adulto do meio universitário.

In this course, we promote a multidisciplinary approach presenting the most recent findings on the topic and challenging the traditional way of considering symbiotic associations as exceptions and not as the rule.

The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects.

Neste encontro, vamos descobrir as potencialidades da utilização do Jamboard - um quadro branco digital gratuito da Google - em trabalhos colaborativos.

Nesta formação, aprenderemos a criar apresentações dentro do Mentimeter, a criar diferentes tipos de slides e a selecionar as configurações mais adequadas aos objetivos pedagógicos.

Nesta formação, iremos abordar as diferentes etapas do processo de planificação de unidades curriculares e refletir conjuntamente em boas práticas sustentadas pela investigação.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.

O evento pretende juntar técnicos, investigadores, estudantes, produtores, industriais e demais agentes da fileira, contribuindo para a atualização de dados sobre o setor e a partilha de conhecimentos sobre as potencialidades da flora portuguesa, para além, das condições edafoclimáticas nacionais que potenciam produtos de elevada qualidade.

This course introduces the field of island biogeography, a discipline that has long influenced other research areas such as macroecology, community ecology, evolution and conservation biology.

Scientists, as the main actors in the production of scientific knowledge, have the responsibility of having an active voice in communicating this knowledge – and that can be achieved for example by a conscious use of the communication tools at their disposal and a better articulation with journalists, among other means.

This course aims at providing students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.

This course aims at providing students with statistical knowledge and tools to manipulate, analyze and visualize biological data with R. It also includes an introduction to modeling, simulations and Bayesian statistics.

Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity.

The course provides essential skills and knowledge that enable the participants to develop climate change adaptation strategies.

The objective of this course is to provide participants with basic knowledge on a) the fundamental aspects of experimental design and b) workflows, platforms and tools to increase reproducibility at all scientific levels.

This is a mostly practical course offering an overview on different community ecology and macroecological methods and software. These will include all steps of a research project, from the optimal sampling of communities to process inference from large-scale patterns of taxon, phylogenetic and functional diversity.

This course aims to walk through the grounds of modern botany studies, covering subjects that have been excluded from most academic curricula.
