Analysis and Topology in Interaction 2011

Conference in Cortona, ItalyInteraction June 6-11, 2011

Purpose of the conference

Topology and Analysis have had numerous fruitful points of contact and mutual application in the past. Nonetheless, we feel that a lot of further insights can be gained from a closer relationship.
We have 23 lectures in total during the week and the general topics we had in mind include: Differential K-theory, elliptic cohomology, surgery theory, foliations, elliptic operators. There will be ample time and opportunity for discussions.
Cortona is a beautiful little town in the Tuscan hills; the conference will be held in "Il Palazzone", a renaissance villa owned by the
Scuola Normale Superiore in Pisa. In the early summer this is the perfect stimulating environment to concentrate on mathematics in general and the interaction of analysis and topolgoy in particular.
Arrival day is Sunday, June 5, talks commence Monday, June 6 in the morning. The conference ends around Friday, June 10, 5 pm; departure day is then Saturday, June 11. There will be no talks Wednesday afternooon.

Conference venue

cortona               palazzone

Cortona is a small town in southern Tuscany, going back Etruscan time, situated on a hill 20km North of Lake Trasimeno. Place of the meeting is the "Palazzone", a 16th century castle 2km outside of Cortona in a typical Tuscan landscape of olive and wine gardens. The Palazzone is owned by the Scuola Normale Superiore di Pisa, who rents it to the Instituto Nazionale di Alta Matematica for several meetings every year.

How to reach Cortona

Il Palazzone is located outside the massive ancient town walls of Cortona, and can be reached by a pleasant walk away from the center of Cortona (about 1,5 Km: you walk from Piazzale Garibaldi on Via Gino Severini and along the way you will find several tourist signs for reaching Il Palazzone).
By Train: There are two railway stations, Terontola-Cortona (10 km to center) and Camucia-Cortona (5 km to center), on the track from Florence to Rome (one hour from Florence, and two hours from Rome, Siena, or Pisa). Both stations are connected to Cortona by bus (or you take a taxi). The train schedules can be obtained from the official timetable of the Italian Railroad company Trenitalia, or alternatively at the German Rail company DB, which also covers non-Italian stations. Bus schedule for Sunday, June 5 from the train stations to the center of Cortona: from Camucia at 16:02, 17:45 and 20:00, from Terontola at 17:32 (buses for other days). Taxi service is offered by the following companies:
  • Giorgio PESCI ++39 360 957648
  • Enzo ADREANI ++39 335 8196313
  • Albino CALERI ++39 368 7386544
  • Dejan PVRULOVIC ++39 348 4023501

By car: Autostrada del Sole (State Highway A1, red on the map):"Valdichiana" Exit. Upon exiting the highway, take the Siena-Perugia State Road (green on the map ) and continue towards Perugia. There are 3 possible turn-offs for Cortona: Cortona via Manzano, Cortona via Laurentana and Cortona via Strada Statale 71 (State Road 71). In this latter case, at Camucia there is a deviation for Cortona and Citt?di Castello (the Umbran-Cortonese Province Road).
The closest airport is Florence, but for intercontinental flights is Rome. Another option is Pisa. From there, continue by train.
