Categorification, quantization and knots

Financiado por Fundação para a Ciência e a Tecnologia.

Referência: FCT Investigator Program, Ref. IF/00998/2015

Investigador responsável: Marko Stosic

The principal goal of this research project is to study the concepts of categorification and quantization, in particular in the context of quantum polynomial link invariants. The main line of this interdisciplinary proposal comes from surprising and exciting connections between the knot theory and homological knot invariants on the mathematical side, and quantum field theory and string theory on the physics side, with outcomes in other fields, like number theory or spectral curves.

Degenerate elliptic and parabolic equations and its applications to front propagation

Financiado por Fundação para a Ciência e a Tecnologia.

Referência: UTA_CMU/MAT/0007/2009

10/08/2011 — 09/08/2014

Investigador responsável: Diogo Gomes

The main goals of the project are the study of PDEs arising in front propagation, namely degenerate elliptic and parabolic equations, their application to concrete problems such as ocean fronts, and the development of numerical tools for the analysis of inverse problems in front propagation. We foresee that the developed techniques will be of interest for other problems also, such as mathematical finance, non-linear filtering, classical mechanics (Aubry-Mather theory and its extensions), mathematical biology, mean field games, homogenization and stochastic PDEs.

Geometrical and Algebraic Structures on the Space of Quantum Theories

Financiado por Fundação para a Ciência e a Tecnologia.

Referência: FCT 02/SAICT/2017/28784

01/10/2018 — 30/09/2021

Investigador responsável: Ricardo Schiappa

This project addresses mathematical structures in the space of all possible quantum theories. The space of all QFTs is infinite-dimensional, with CFT fixed-points linked by paths corresponding to RG flows. These CFTs are the building blocks of all possible quantum theories (including theories of quantum gravity and black holes). Our goal is to understand the space of all theories by first understanding some special subsets. We use complementary approaches, such as Resurgent Analysis, Bootstrap Techniques, and Localisation. These approaches solve quantum theories described by random matrix models, CFTs in diverse dimensions, and quantum theories with localisable observables. The very same theory may be approachable using these different techniques, leading to complementary information. By solving different special sets of quantum theories, we expect to describe geometrical and algebraic structures on local patches of the full space of quantum theories.

Higgs bundles and character varieties

Financiado por Fundação para a Ciência e a Tecnologia.

Referência: PTDC/MAT/120411/2010

01/03/2012 — 28/02/2015

Investigador responsável: Carlos Florentino

This project deals with the geometry and topology of two classes of intimately related spaces: on one side, we have the moduli spaces of Higgs bundles or other holomorphic objects over a complex manifold, and on the other side we have character varieties, which are moduli spaces of representations of a finitely generated group into a Lie group.

In this project, we plan to address some of the facets of this profitable connection that are still undeveloped. Our approach will be a natural continuation of many important established results that were obtained in recent years by many mathematicians, including results from members of the project.

Modeling and Analysis of Coastal Hydrodynamics and Erosion

Financiado por Fundação para a Ciência e a Tecnologia.

Referência: UTAP-EXPL/MAT/0017/2017

01/11/2018 — 31/10/2020

Investigador responsável: Juha Videman

Coastal ocean regions around the world are threatened by a variety of factors and the increasing risk and associated impacts have catalysed efforts to increase our understanding of the coastal ocean environment and our ability to make quantitative predictions of coastal hydrodynamics. In this project, we propose to build a numerical code based on hybridised discontinuous finite element methods for studying coastal hydrodynamics and sediment erosion with specific emphasis on regions of the Texas-U.S. and Portuguese coasts. Our goal is to develop, analyse and implement high-order finite element methods on unstructured meshes which include appropriate wave physics at various wave-lengths and wave numbers. This allows for capturing multi-scale wave physics from deep ocean basins to the continental shelf to complex coastal systems including barrier islands, inlet, bays, and estuaries.
