From linear to bilinear pseudodifferential operators
Linear pseudodifferential operators arise as natural generalizations
of partial differential operators with variable coefficients or, more
generally, translation invariant operators. We start with a heuristic
motivation for the introduction of these objects and some classical
classes of symbols of pseudodifferential operators. We make then the
transition to bilinear pseudodifferential operators, which generalize
now the product of two functions and their derivatives. We dedicate the
remainder of our talk to presenting some basic facts and results about
the boundedness of bilinear pseudodifferential operators.
Refreshments will be served at 2:45 p.m. in the Faculty Lounge, Math Annex (Room 1115).
