\(\mathbb Q_p\)-linear continuous Galois equivariant maps from \(\mathbb C_p\) into itself
Let \(K\) be a finite extension of \({\mathbb Q}_p\) with the absolute Galois group \({\mathcal G}_K\). The author presents a new proof of Fontaine's result that a \({\mathbb Q}_p\)-linear, continuous and \({\mathcal G}_K\)-equivariant application from \({\mathbb C}_p\) into itself is a homothety.
