I learned from the previous topics that a vectors space is NOT Hilbert space, however an inner product forms a Hilbert space if it is complete.

Can two eigenvectors which are linearly independent form a Hilbert space in their inner product?

e_1 = [x_1, y_1]

e_2 = [x_2, y_2]

##\langle e_1, e_2 \rangle## ?

Thanks
