DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CGP-MP/35/">
 Perturbative connection formulas for Heun equations</a>\nby Oleg Lisovyy (
 Université de Tours) as part of IBS-CGP Mathematical Physics Seminar\n\n\
 nAbstract\nConnection formulas relating Frobenius solutions of linear ODEs
  at different Fuchsian singular points can be expressed in terms of the la
 rge order asymptotics of the corresponding power series. I will show that 
 for the Heun equation and some of its confluent versions\, the series expa
 nsion of the relevant asymptotic amplitude in a suitable parameter can be 
 systematically computed to arbitrary order. This allows to check a recent 
 conjecture of Bonelli-Iossa-Panea-Tanzini expressing the Heun connection m
 atrix in terms of quasiclassical Virasoro conformal blocks.\n
