TENORS Doctoral Days – Tensors: geometry, optimization, and applications

Introduction

The title of the Doctoral Days is “Tensors: geometry, optimization, and applications“

The aim of this event is to offer DCs of TENORS an academic environment to present their latest work, discuss with senior researchers and share ideas with other international colleagues in the domain.

The DCs will be in charge of the organization of the Doctoral days, in coordination with the network partners and coordinators. TENORS DCs will invite external speakers, coordinate and organize the presentations, organize tutorials and training sessions for complementary skills.

Getting to Florence

Getting to Florence by Air

The Florence airport (FLR) is called Amerigo Vespucci and is situated on the north-west outskirts of Florence, just 4 km from the city center. The airport can be reached from the center of Florence, driving the whole length of Viale Guidoni up to the road leading to the “Firenze Nord/Firenze Mare” superhighway (A1 and A11).

The center can be reached in about 15 minutes by taxi, and in about 20 minutes with the Tramway T2 line, operating between the airport and the central railway station of Santa Maria Novella. See below for more details.

The Florence Airport is connected to some of Europe’s major airports such as Amsterdam, Barcelona, Brussels, Bucharest, Frankfurt, Geneva, London Gatwick, Madrid, Munich, Paris Charles de Gaulle and Vienna. There are also flights to and from the following Italian cities: Bologna, Cagliari, Catania, Milan Malpensa, Olbia, Palermo, Rome Fiumicino, Turin and Verona.

The airport is also easily reached from other Tuscan cities as it is just off the A11 and A1 Firenze Nord exit : Prato (8 km), Pistoia (24 km), Montecatini (36 km), Lucca (65 km), Siena (68 km), Arezzo (77 km), Pisa (86 km), Carrara and Massa (117 km), Grosseto (143 km), as well as from the sea and its ports: Livorno (115 km) and Piombino (170 km).

Getting to/from downtown Florence

From the Florence airport, you can get to downtown Florence either with a taxi (read more information on moving around Florence with a taxi here) or with the Tramway T2 line that you can take from the airport to the central Santa Maria Novella train station (SMN), stop Alamanni Stazione. It takes about 20 minutes. The service runs daily, including Sundays and holidays.

A one-way ticket costs 1.50 euros. Tickets can be purchased at automatic machines, the map can be viewed here
