    • Abstract

       

      A polynomial knot in $\mathbb{R}^n$ is a smooth embedding of $\mathbb{R}$ in $\mathbb{R}^n$ such that the component functions are real polynomials. In the earlier paper with Mishra, we have studied the space $\mathscr{P}$ of polynomial knots in $\mathbb{R}^3$ with the inductive limit topology coming from the spaces $\mathscr{O}_d$ for $d\geq 3$, where $\mathscr{O}_d$ is the space of polynomial knots in $\mathbb{R}^3$ with degree $d$ and having some conditions on the degrees of the component polynomials. In the same paper, we have proved that the space of polynomial knots in $\mathbb{R}^3$ has the same homotopy type as $S^2$. The homotopy type of the space is the mere consequence of the topology chosen. If we have another topology on $\mathscr{P}$, the homotopy type may change. With this in mind, we consider in general the set $\mathscr{L}^n$ of polynomial knots in $\mathbb{R}^n$ with various topologies on it and study the homotopy type of the respective spaces. Let $\mathscr{L}$ be the union of the sets $\mathscr{L}^n$ for $n\geq 1$. We also explore the homotopy type of the space $\mathscr{L}$ with some natural topologies on it.
