Ireland is not a member of the Schengen Area and a Schengen visa is not valid for travel to Ireland. A passport is required for travel to Ireland from any other state (including the United Kingdom where it is not an immigration requirement, but airlines require identification documents and many will only accept a passport).

Please see this advice from the Irish government on whether or not you need to apply for a visa in advance of travel to Ireland to attend an academic conference, according to your nationality as shown on your passport or travel document. Participants who do need a visa can find advice there on the online application process and the likely duration of the wait for approval.

Dublin Airport is the main arrival point for international visitors to Ireland and has daily direct flights to many locations worldwide, particularly in Europe and North America. It is connected by multiple daily flights to the major European hubs such as Frankfurt, Heathrow, Amsterdam and Charles de Gaulle.

Dublin Airport provides assistance for travellers with constrained mobility, which can be arranged in advance.

Travellers from Dublin Airport to the United States clear US Immigration and Customs in Dublin, which requires a little extra time in Dublin Airport before scheduled departure.

There are frequent buses which depart from Dublin airport to the center of the city. More information about the different bus services available from the airport can be found at the airport website. One can also catch a taxi from the taxi ranks. Please follow signs in the airport to an official taxi rank booth.

The entire meeting will take place in the Hamilton Building, which is located on the far east side of Trinity's main campus. Although the Hamilton Buiding has an address on Westland Row, it cannot be entered by the public from this side. Rather, one should enter campus either at the Pearse Street entrance or the Lincoln Gate entrance. From either entrance, one can enter the Hamilton Building at one of two points (here or here).

All talks will take place in the Maxwell lecture theater. Maxwell is on the First Floor. It can be accessed from either entrance, but it is more convenient to ascend the external stairs located here and enter the building. Maxwell is located just to the right of the entrance.

Viral geometry as a key to understanding viral infections

Insights into the geometric principles underpinning viral particles provide a key to uncovering the mechanisms by which viruses replicate and infect their hosts. Using novel geometric and topological descriptors of virus architecture in combination with stochastic simulations, I will demonstrate how viral geometry impacts on different aspects of a viral life cycle, including virus assembly and genome release. These results pave the way to innovation in antiviral therapy and virus nanotechnology.

Turning gradware into software and impact

HiGHS is open-source optimization software for linear programming (LP), mixed-integer programming (MIP) and quadratic programming (QP). This talk will give an insight into the state-of-the-art techniques underlying its solvers, most of which were originally written as “gradware” by PhD students. Independent benchmark results will be given to justify the claim that HiGHS is the world’s best open-source linear optimization software, in particular when solving LPs by interior point. However, the interior point solver can still be uncompetitive with commercial solvers. This has been noticed particularly in the context of energy systems, and led to major funding for the development of a new interior point solver. This talk will discuss our work in this area, as well as providing an update on more general advances in HiGHS. The team developing HiGHS was responsible for a 2021 REF Impact Case Study, and has the potential to generate further Impact for the next REF, so observations on the creation of Impact via software development will be given.

A survey of the open problems of turbulence and finite-time singularities in fluid mechanics, and their relation with phase synchronization and integrable systems

In this talk I will present a survey of my research on the dynamics of nonlinear systems, in the context of the open problems of turbulence and finite-time singularities in fluid mechanics. I will show the connections of this research with the phenomenon of phase synchronization in networks and with the theory of integrable systems. Also, time permitting, I will explain how my work was impacted by areas of "pure" mathematics, such as number theory (e.g. the search for exact resonances in nonlinear wave systems) and non-associative algebras (e.g. the search for evolution laws of genetics).

Reversing irreversible: super-resolution and filtering for PDEs from noisy data

A super-resolution problem, arising in many applications, can be formulated as follows: given noisy data, which is known to be generated by a non-linear PDE, one needs to reconstruct PDE’s solution on a high-resolution grid, and reduce the impact of the noise. We introduce a class of linear possibly irreversible operations such that applying an operator from this class to data reduces noise at the price of loosing information (e.g. averaging or smoothing) but the lost information can be efficiently recovered by a state estimation algorithm, which provides a continuos reconstruction of PDE’s solution hence allowing to “super-resolve” the solution on any grid. The algorithm is based on minimax estimation. We illustrate the efficacy of the algorithm on a super-resolution problem for Navier-Stokes equations in two spatial dimensions.
