DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ENAAS/72/">N
 ovikov algebras and multi-indices in regularity structures</a>\nby Yvain B
 runed (University of Lorraine\, France) as part of European Non-Associativ
 e Algebra Seminar\n\n\nAbstract\nIn this talk\, we will present multi-Novi
 kov algebras\, a generalisation of Novikov algebras with several binary op
 erations indexed by a given set\, and show that the multi-indices recently
  introduced in the context of singular stochastic partial differential equ
 ations can be interpreted as free multi-Novikov algebras. This is parallel
  to the fact that decorated rooted trees arising in the context of regular
 ity structures are related to free multi-pre-Lie algebras. This is a joint
  work with Vladimir Dotsenko.\n
