# BijectiveMapsfromInjectivemaps $\mathbb{R}^{n} \to \mathbb{R}^{m}$

Hi--

Let $f: \mathbb{R}^{n} \to \mathbb{R}^{m}$ be an Injection. If injection for $n>m$ then can n>m$. Can$f$be continuous. ? Why.? I got this question in my mind when i I was trying to find a continuous map from$\mathbb{R}^{2} \\mathbb{R}^{2}$to \mathbb{R}$.$\mathbb{R}$.

# Bijective Maps from $\mathbb{R}^{n} \to \mathbb{R}^{m}$

Hi--

I got this question in my mind when i was trying to find a continuous map from $\mathbb{R}^{2} \to \mathbb{R}$.
