The discreet charm of the square root

We present a version for the general readership of our article (Amster y Cid, 2022) in which we show how the complex square root allows us to prove in a very simple manner various topological results in the plane, as deep as the Brouwer Fixed Point Theorem and the Invariance of Domain Theorem, as we...

Presentamos una versión divulgativa de nuestro artículo (Amster y Cid, 2022) en el que mostramos cómo la raíz cuadrada compleja nos permite demostrar de una forma muy sencilla diversos resultados topológicos en el plano, tan profundos como el Teorema de Brouwer y el Teorema de Invariancia del Dominio, así como del Teorema Fundamental del Álgebra.
