The singular fibre of the Hitchin map
Peter B. Gothen, André Oliveira
Given any line bundle L of positive degree, on a compact Riemann surface, let be the moduli space of L-twisted Higgs pairs of rank 2 with fixed determinant isomorphic to $Λ…
Asymptotic behaviour of the non-autonomous 3D Navier-Stokes problem with coercive force
Dmitry Vorotnikov
We construct pullback attractors to the weak solutions of the three-dimensional Dirichlet problem for the incompressible Navier-Stokes equations in the case when the external force…
Multiplicity-free Skew Schur functions with full interval support
Olga Azenhas, Alessandro Conflitti, Ricardo Mamede
It is known that the Schur expansion of a skew Schur function runs over the interval of partitions, equipped with dominance order, defined by the least and the most dominant Little…
Fine compactified Jacobians
Margarida Melo, Filippo Viviani
We study Esteves's fine compactified Jacobians for nodal curves. We give a proof of the fact that, for a one-parameter regular local smoothing of a nodal curve , the relative sm…
Extremal Index, Hitting Time Statistics and periodicity
Ana Cristina Moreira Freitas, Jorge Milhazes Freitas, Mike Todd
We give conditions to prove the existence of an Extremal Index for general stationary stochastic processes by detecting the presence of one or more underlying periodic phenomena. T…
Extreme Value Laws in Dynamical Systems for Non-smooth Observations
Ana Cristina Moreira Freitas, Jorge Milhazes Freitas, Mike Todd
We prove the equivalence between the existence of a non-trivial hitting time statistics law and Extreme Value Laws in the case of dynamical systems with measures which are not abso…
A note on the "Smith is Huq" condition
Nelson Martins-Ferreira, Tim Van der Linden
We show that two known conditions which arose naturally in commutator theory and in the theory of internal crossed modules coincide: every star-multiplicative graph is multiplicati…
Crossover to the KPZ equation
Patrícia Gonçalves, Milton Jara
We characterize the crossover regime to the KPZ equation for a class of one-dimensional weakly asymmetric exclusion processes. The crossover depends on the strength asymmetry $an^{…
Perfect category-graded algebras
Ana Paula Santana, Ivan Yudin
In a perfect category every object has a minimal projective resolution. We give a criterion for the category of modules over a categorygraded algebra to be perfect.
On Jacobi quasi-Nijenhuis algebroids and Courant-Jacobi algebroid morphisms
Raquel Caseiro, Antonio De Nicola, Joana M. Nunes da Costa
We propose a definition of Jacobi quasi-Nijenhuis algebroid and show that any such Jacobi algebroid has an associated quasi-Jacobi bialgebroid. Therefore, also an associated Couran…
On a forward-backward stochastic system associated to the Burgers equation
Ana Bela Cruzeiro, Evelina Shamarova
We describe a probabilistic construction of -regular solutions for the spatially periodic forced Burgers equation by using a characterization of this solution through a forwar…
Presentations of Schutzenberger groups of minimal subshifts
Jorge Almeida, Alfredo Costa
In previous work, the first author established a natural bijection between minimal subshifts and maximal regular J-classes of free profinite semigroups. In this paper, the Schützen…
