In this talk we will discuss a new framework for classifying knots by exploring the neighborhood of knot embeddings in the space of (collections of) simple open curves in 3-space with no constraints at their endpoints. The latter gives rise to a knotoid (or linkoid) spectrum of a knot that consists of a knot-type knotoid and pure knotoids. We will examine to what extent the pure knotoids of the knotoid spectrum determine the knot type. For example, we will prove that the pure knotoids in the knotoid spectra of a knot, which are individually agnostic of the knot type, can distinguish knots of Gordian distance greater than one. We will also prove that the open curve neighborhood of, at least some, embeddings of the unknot can be distinguished from any embedding of any non-trivial knot that satisfies the cosmetic crossing conjecture. Topological invariants of knots can be extended to their open curve neighborhood to define continuous functions in the neighborhood of knots. We will discuss their properties and prove that invariants in the neighborhood of knots may be able to distinguish more knots than their application to the knots themselves. For example, we will prove that an invariant of knots that fails to distinguish mutant knots (and mutant knotoids), can distinguish them by their neighborhoods, unless it also fails to distinguish non-mutant pure knotoids in their spectra. Studying the neighborhood of knots opens the possibility of answering questions, such as if an invariant can detect the unknot, via examining possibly easier questions, such as whether it can distinguish height one knotoids from the trivial knotoid.
