报告摘要： In this talk, we first recall the notion of (noncommutative) Poisson conformal algebras and give some constructions. Then we study the relations between formal distribution (noncommutative) Poisson algebras, coefficient (noncommutative) Poisson algebras and (noncommutative) Poisson conformal algebras. Next, we introduce the notion of conformal formal deformation of commutative associative conformal algebras and show that Poisson conformal algebras are the corresponding semi-classical limits. At last, we introduce the cohomology of (noncommutative) Poisson conformal algebras and use this cohomology to study their deformations.
