For plates coated with soft film, the impact dynamics remains unknown. In this study, we focus on developing an impact model for such coated plate. Webalgebraic and homotopy theoretic techniques combined with computational tools like spectral sequences to compute Picard groups of E ∞-ring spectra. Picard groups were first studied in number theory as class groups of number fields. Later this notion was generalised to define the Picard group for a schemeX.

The first and simplest homotopy group is the fundamental group, denoted which records information about loops in a space. Intuitively, homotopy groups record information about the basic shape, or holes, of a topological space. To define the n-th homotopy group, the base-point-preserving maps from an n-dimensional sphere sche form nyc

"WebA monotone homotopy is a homotopy composed of simple closed curves which are also pairwise disjoint. In this paper, we prove a “gluing” theorem for monotone homotopies; we show that two monotone homotopies which have appropriate overlap can be replaced by a single monotone homotopy.
