Hello I've got a problem : let be a normed vectorial space E, N and A an continue automorphism.
I suppose E is complete. So by the banach theorem
$$A^{−1}$$
is continue.
So now let be f a k lipshitz application with
$$k<\frac{1}{||A^{−1}||}$$.
.
I'd like to show that f + A is an homomorphism.
I don't even know how to start.
Have you got any idea please?
Thank you in advance and have a nice afternoon.
