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.
