A conjectu re by Zamolodchikov relates them to quasiclassical limit of conformal bloc ks of the Virasoro algebra. I will explain an extension of this conjectura l relation to another class of accessory parameter functions that are defi ned by inverting all-order Bohr-Sommerfeld periods for the confluent and b iconfluent Heun equation.\n\nSeminar Physique Mathématique\n En ligne/Web - Svp remplir ce formulaire/Please fill in this form: https://forms.gle/S1N cNQ8BxkzfAXcj9\n DTSTART:20211130T203000Z DTEND:20211130T213000Z SUMMARY:Oleg Lisovyy (Université de Tours) URL:/mathstat/channels/event/oleg-lisovyy-universite-d e-tours-335171 END:VEVENT END:VCALENDAR
