DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/124/">T
 owards a theory of homotopy structures for differential equations: First d
 efinitions and examples. Part 2</a>\nby Vladimir Rubtsov (Université d'An
 gers) as part of Geometry of differential equations seminar\n\n\nAbstract\
 nWe define $A_\\infty$-algebra structures on horizontal and vertical coho
 mologies of (formally integrable) partial differential equations.\n\nSince
  higher order $A_\\infty$-algebra operations are related to Massey product
 s\, our observation implies the existence of invariants for differential 
 equations that go beyond conservation laws.\n\nWe also propose notions of 
 formality for PDEs\, and we present examples of formal equations.\n
