Classification of First Order Linear Partial Differential Eq

Click For Summary
SUMMARY

First order linear partial differential equations (PDEs) can be classified into hyperbolic, parabolic, and elliptic categories based on their characteristics. Not all first order linear PDEs are hyperbolic; some can be classified as elliptic. The classification relies on specific definitions and characteristics outlined in reputable references on PDEs. For accurate classification, utilizing resources such as the method of characteristics is essential.

PREREQUISITES
  • Understanding of first order linear partial differential equations
  • Familiarity with the method of characteristics
  • Knowledge of PDE classification criteria
  • Access to authoritative references on partial differential equations
NEXT STEPS
  • Research the method of characteristics for classifying PDEs
  • Study the definitions and properties of hyperbolic, parabolic, and elliptic PDEs
  • Explore authoritative textbooks or online resources on partial differential equations
  • Practice classifying various first order linear PDEs using examples
USEFUL FOR

Mathematicians, physics students, and engineers who are working with partial differential equations and need to classify them for applications in various fields such as fluid dynamics and heat transfer.

Not all linear first order PDEs are hyperbolic, no.
The Quora post you point to actually spells that out... the author says that some are elliptical etc.

You classify a PDE according to the definitions of the classes... for that detail, you need a good reference on PDEs.

Turns out to be an easy Google (use, "classifying PDEs") to get for instance:
