Hi,


I am interested in the Jacobi method to solve partial differential equation of first order. I would like to have a hint about a good book to study this subject.


Thanks in advance



Jacobi method on first order partial differential equations
Chapter VII of É. Goursat's book, [Leçons sur l'intégration des équations aux dérivées partielles du premier ordre](http://name.umdl.umich.edu/ACR1803.0001.001), exposes the method and ends with 14 examples of applying it (pp. 168-169).
