Welcome

We are happy to welcome you to Milan for the 9th meeting of the Conference Series Computability in Europe. Computability in Europe �01� (CiE �01�) follows the CiE �01� Turing Centenary Conference in celebrating the key influence of Turing’s work on the specific focus of the CiE conference series for the development of a multi-disciplinary view of modern computation and computability. The questions of “How does nature compute?” or, more generally, of “What is computation in nature?” are strongly related to the title The Nature of Computation that emphasizes the special focus of CiE1� on the unexpected and strong changes that studies on Nature have brought to several areas of mathematics, physics, and computer science.

The Nature of Computation is co-located with Unconventional Computation and Natural Computation. They share one plenary invited talk, given by Endre Szemerédi (Budapest & Piscataway NJ), winner of the Abel Prize in �01�, and two tutorials, one by Grzegorz Rozenberg (Leiden & Boulder CO) and the other by Gilles Brassard (Montréal QC).

This booklet contains all the information you need during the conference. It includes a map of the modern campus of the University of Milano-Bicocca, where you can find several points of interest, shops, bars, and restaurants. You can also find some information on exhibitions that are scheduled during the week of the conference. Don’t miss a visit to Hangar Bicocca, a contemporary art space just outside the campus. A must for anyone visiting Milan includes a walk through the beautiful Galleria Vittorio Emanuele, along with a stop at The World of Leonardo, the most important interactive and multidisciplinary exhibition dedicated to the artist and engineer Leonardo da Vinci. The exhibition also shows Leonardo’s work on The Last Supper (the painting in the background of our CiE1� poster). You will find that Milan is a very active city with many cultural events and attractions.

We wish you a fruitful, stimulating, and enjoyable conference in Milan.

All the best,Paola Bonizzoni and the organizing committee

17:�0 - 18:�0Tuesday 2 July

Women in Computer Science and Mathematics face particular challenges in pursuing and maintaining academic and scientific careers. Women are significantly underrepresented at all levels of the academic pipeline, while the very few female students involved in Computing and Mathematical Research need to be aware of their talent and role in the scientific community. Indeed, the scarcity of senior women academicians produces the lack of critical information about the culture and content required for pursuing careers in the mathematical sciences.

The Women in Computability workshop aims to bring together women in Computing and Mathematical research to present and exchange their academic and scientific experience with young researchers. The meeting will offer the CIE scientific community the opportunity to encourage young students, especially young female researchers, to have active careers in the mathematical and computational sciences. The CIE community will also discuss on the status of women in Computability research.

The confirmed speakers are:- Irene Finocchi (University of Rome, Italy)- Laxmi Parida (IBM Thomas J. Watson Research Center, USA)- Liesbeth De Mol (Universiteit Gent, Belgium)

Under the name Elsevier Women in Computability (WiC), the publisher Elsevier (more precisely, the journals “Annals of Pure and Applied Logic” and “Theoretical Computer Science”) is continuing the programme “Increasing representation of female researchers in the computability community” originally funded by the Elsevier Foundation (�008-�010).

This programme will finance the WiC workshop at CiE �01� with the traditional WiC dinner for workshop participants afterwards and offer up to four grants with modest support (up to �00 EUR) for junior female researchers to attend CiE �01�. Every registered junior female researcher is eligible to apply. Preference will be given to researchers who present a paper (contributed paper or informal talk).

EXPOSITIONSNumerous exhibitions, art events and expositions all rotate around the city. We point out:

Leonardo3 - Il Mondo di Leonardo (Leonardo3 - The World of Leonardo)The most important interactive and multidisciplinary exhibition dedicated to the artist and engineer Leonardo da Vinci and his machines is open in Milan.

Address: Piazza della Scala Price: €1� Mon-Sun: 10:00am-11:00pm Web: www.leonardo�.net

Modigliani, Soutine e gli Artisti Maledetti - La collezione Neter (Modigliani, Soutine and the Coursed Artists - The Neter Collection)Presented with great success at the Pinacothèque de Paris, the exhibition brings to Milan more than 1�0 masterpieces created by Amedeo Modigliani and the artists who lived and painted in Paris, in the Montparnasse area, in the early ‘900. For the first time in Italy works from the extensive collection of Jonas Netter (Strasbourg 18�8 - Paris 19��), acute connoisseur of talent, including Soutine, Utrillo, Suzanne Valadon and, of course, Modigliani.

Address: Palazzo Reale Price: €11 Mon: �:�0pm-7:�0pm Tue-Sun: 9:�0am-7:�0pm (Thu & Sat till 10.�0pm) Web: www.mostramodigliani.it

HangarBicoccaHangar Bicocca is a space near the University of Milano-Bicocca and devoted to the production, exhibition and promotion of contemporary art. The current exhibition presents Mike Kelley: Eternity is a Long Time, about the work of the late American artist Mike Kelley (Detroit, 19�� – Los Angeles, �01�). HangarBicocca also puts on an exciting calendar of events offered to the public completely free of charge: HB Kids offers creative adventures, films and activities for children. HB Public has a programme of film festivals, guided tours, meetings with the curator and artists, and cycle rides to explore the Bicocca district.

Address: via Chiese, � Thu-Sun: 11am-11pm Web: www.hangarbicocca.org/home-en-US/
