Understanding the mathematical nature of PDE
Hello everyone,
I am fledgling in the domain. I wanted to learn how to identify the mathematical nature of PDE, whether they are hyperbolic/parabolic/elliptic in space and time. I was taught how to make such categorization for a PDE in 2 independent space variables, but how do we go about it when a time derivative is present? And how does understanding the nature of equation and finding characterisitics further help in our errand of solving the equation numerically? I have read some books about it, but I was not able to understand the physical meaning or visualize how exactly the conclusions were drawn :confused:
Any help would be appreciated.
Regards,
