 n\nThematic 3-weeks programme at the Institut Henri Poincaré\, Paris\, Ma
 y 18th to June 4th\, 2027.\nBeware: It was reported to us that scammers a
 re sending to participants fraudulent e-mails about accommodation/fees. Pl
 ease be particularly cautious about e-mails not coming from the organisers
  nor from an @ihp.fr address. \nREGISTRATION IS FREE\, HOWEVER MANDATORY.
 \nPresentation of the programme\nIn recent years\, there have been major a
 dvances using techniques from Descriptive Set Theory to show\, in a rigoro
 us way\, that many classical problems in Dynamical Systems are impossible 
 to solve. In this context\, a problem that can be set in a Polish space is
  said to be impossible to solve if it cannot be settled using inherently c
 ountable techniques. These groundbreaking results mostly lie in Ergodic Th
 eory\, with further significant advances in Topological and Smooth Dynamic
 al Systems.\nOne main goal of this program is to further enhance interacti
 ons between Descriptive Set Theory and Dynamical Systems. It brings togeth
 er researchers from different fields to settle some of the most famous pro
 blems in dynamics dating to the mid-20th century.\nA second main goal is t
 o expand applications of the techniques from Descriptive Set Theory to oth
 er areas of mathematics.\nWeek 1\nThe program begins with lectures introdu
 cing the basic impossibility techniques and lectures explaining fundamenta
 l concepts in areas of potential applications.\nWe plan to have tutorials 
 on:\n\nImpossibility Results\nErgodic Theory\nSymbolic Dynamics\nSmooth Dy
 namical Systems\n\nAdditionally\, there will be Research Talks and Exposit
 ory Lectures (primarily in Ergodic Theory and Descriptive Set Theory).\nWe
 ek 2\nResearch talks in Descriptive Set Theory\, Ergodic Theory\, Smooth a
 nd Symbolic Dynamics\, as well as Expository Lectures\, including on:\n\nI
 mpossibility Results in Ergodic theory\nComplexity Theory\nFlexibility and
  Rigidity\n\nMoreover\, we will have Problem and Discussion Sessions.\nWee
 k 3\nTopical Days (particularly Complex Dynamics with tutorial)\; Problem 
 Sessions\nInvited Speakers include:\nAdam Kanigowski\,  Georgia TechAsger
