Partial differential equations is a many-faceted subject.Created to describe the mechanical behavior of objects such as vibrating strings and blowing winds,it has developed into a body of material that interacts with many branches of math-ematics,such as differential geometry,complex analysis,and harmonic analysis,as well as a ubiquitous factor in the description and elucidation of problems in mathematical physics.
