(G2G2-Summer School) DTSTART;VALUE=DATE-TIME:20200629T080000Z DTEND;VALUE=DATE-TIME:20200704T180000Z DTSTAMP;VALUE=DATE-TIME:20190718T162106Z UID:indico-event-13@cern.ch DESCRIPTION:Satellite event of the 8th European Congress of Mathematics\n \n\n\nG2G2-Summer School is associated with G2G2-Minisymposia of 8ECM. I t belongs to the G2-series that are about strong and beautiful mathemati cs\, especially those involving group actions on combinatorial objects.\n\ nThe main goal of G2G2-Summer School is to bring together experts and stud ents to exchange ideas and to enrich their mathematical horizons with focu s on computational methods in mathematics and vertex operator algebras. We organize two minicourses each of which is presented in ten lectures inc luding two problem solving sessions\, and eight colloquium talks to let pa rticipants see order and simplicity from possibly new perspectives and sha re insights with experts. The two topics are linked together through Major ana Theory\, which can be viewed as a finite dimensional extraction of ver tex operator algebras.\n\nComputer algebra systems are an invaluable resea rch tool in finite group theory. Their use is becoming increasingly widesp read and it is now virtually compulsory for young mathematicians to have s ome experience with computational methods. GAP is one of the pre-eminent c omputer algebra systems. Theory of vertex operator algebras holds a promin ent position in recent studies of algebraic combinatorics as a rich source of combinatorial structures with actions of finite groups. However\, othe r connections between vertex operator algebras and finite groups have been largely unexplored\, despite a large body of research that has now develo ped in the field of vertex operator algebras. It is crucial that these two rich areas of mathematics are once again united and the G2G2 school offer s the perfect opportunity for this. Any young researcher interested in alg ebraic combinatorics and finite groups would benefit enormously from these two minicourses as well as\, of course\, the opportunity to present their own work and to discuss research with the other attendees.\n\nVenue: The Summer School will be held at Hotel Planja\, Rogla. Situated at around 150 0m above sea level\, its beautiful natural scenery provides pleasant clima te conditions and stimulating working environment.

As such\, the general theme of this conference will be the mathematical topics that Paul has worked on over the years (which all have relationships to the q- Onsager algebra). These topics include the following:\n\n• Topics in alg ebraic graph theory\, such as distance-regular graphs\, association scheme s\, the subconstituent algebra\, and the Q-polynomial property\;\n\n• To pics in linear algebra\, such as Leonard pairs\, tridiagonal pairs\, billi ard arrays\, lowering-raising triples\, and a linear algebraic approach to the orthogonal polynomials of the Askey scheme\;\n\n• Topics in Lie the ory\, such as the tetrahedron algebra and the Onsager algebra\;\n\n• Top ics in algebras and their representations\, such as the equitable presenta tion of U_q(sl_2)\, the q-tetrahedron algebra\, the mathematical physics o f the q-Onsager algebra\, and the universal Askey-Wilson algebra.\n\nDate: \n\n13 – 18 July 2020\n\nLocation:\n\nKranjska gora\, Slovenia\n\nOrgani zers: \n\nŠtefko Miklavič (University of Primorska\, Andrej Marušič Institute\, Slovenia) \nContact: stefko.miklavic@upr.si\n\nMark Maclean (Mathematics department\, Seattle University\, USA)\nContact: macleanm@se attleu.edu\n\nhttps://conferences.famnit.upr.si/event/15/ LOCATION:Kranjska gora URL:https://conferences.famnit.upr.si/event/15/ END:VEVENT END:VCALENDAR
