*** 108th Peripatetic Seminar on Sheaves and Logic *** Terrasini (Palermo), Italy *** September 16th-17th, 2023 + satellite event September 15th, 2023. Dear colleagues and friends, We are pleased to announce that the 108th Peripatetic Seminar on Sheaves and Logic will be held under the auspices of the University of Palermo in Terrasini (Palermo, Italy), on the weekend September 16th-17th, 2023. A satellite event "Logic and Algebra" will be held in the same place on Friday September 15th, 2023. We have four invited speakers for the satellite event on Friday: Maria Manuel Clementino (University of Coimbra), Vincenzo Marra (Universita' degli Studi di Milano), Zurab Janelidze (Stellenbosch University) and Enrico Vitale (Universite catholique de Louvain). As usual for PSSLs, there is no conference fee, but you need to register in order to attend the meeting. Please register before August 15th, 2023. We are making this preliminary announcement well in advance, as we hope that many of you will be able to join us and contribute with their talks. If you wish to give a talk, please register on the website and then send an email with the title of your talk and a short abstract to giuseppe.metere@unipa.it. There is no deadline, but please consider that talk proposals will be accepted as long as there there are available slots in the PSSL schedule. If you have any questions, please feel free to contact us. More info and updates on the conference website: https://sites.google.com/view/beppemetere/pssl-108/ Info on the location. The conference will take place in the historical site of Palazzo d'Aumale, facing the sea front, in the centre of Terrasini. The building was built in the XIX century under Don Vincenzo Grifeo, Prince of Partanna and Duke of Floridia. Then it was acquired by the Duke of Aumale (hence the name), the fifth son of King Louis-Philippe I of the French, to be used as wine warehouse. Since 2001, Palazzo d'Aumale houses some collections of archeologic and etno-anthropologic interest. Terrasini is a small pretty village close to the beach, five minutes away from Palermo airport. Please consider that this is a popular tourist destination: we strongly recommend participants to book their accommodation in advance. Some suggestions can be found on the conference website. We hope to see you in September!
