Is There a Vector Space Defined by Canonical Boundary Conditions?

Click For Summary
SUMMARY

The discussion centers on proving the existence of a vector space defined by specific boundary conditions in the context of partial differential equations (PDEs). The key conclusion is that to establish this vector space, one must demonstrate that any linear combination of functions satisfying the boundary conditions also satisfies those conditions. The example provided illustrates that if a function and its derivative equal zero at a boundary point, then their linear combination will also equal zero, confirming the vector space property.

PREREQUISITES
  • Understanding of partial differential equations (PDEs)
  • Familiarity with vector spaces and linear combinations
  • Knowledge of boundary conditions in mathematical analysis

how do you prove/show that there really is a vector space defined by certain boundary conditions?

unfortunately this part of pde's was glossed over in my professor's lecture notes and I don't recall him talking about it in class.

haha actually I think I just realized how to do it, you have to show that any two functions that any combination of funcions that meet the conditions must be a function that also meets the condition, which will be met with any set of boundary conditions where the function =0 at that point.

af(0) +bf'(0)=0+0=0is this correct?
