Hello!
while solving a linear differential equation of general form we often use the
differential operator"D" as an algebraic quantity.
Say in expansion of f(d)=[1/(D-1)]q(x) we write f(d) = (D-1)^-1 and expand using binomial expansion.But binomial expansion is valid only for |D|<1 right?!...
I wonder how to interprete an "operator D" to be less than 1 or not...can somebody
