Loop spaces in derived algebraic geometry I will introduce various loop spaces, including rational, trigonometric, and elliptic loop spaces, and discuss their degenerations. I will explain how the HKR filtration can be derived from deformation to the normal cone. If we have time, I will also discuss the lift to the sphere spectrum, which leads to a filtration of topological Hochschild homology. |
