Logarithmic Gysin sequences for regular immersions
Abstract
For a regular immersion of schemes Z X and a cohomology theory of fs log schemes, we formulate the logarithmic Gysin sequence using the "logarithmic compactification" (BlZ X,E) instead of the open complement X-Z, where E is the exceptional divisor. We show that all A1-invariant cohomology theories produced from motivic spectra and various non A1-invariant cohomology theories like Nygaard completed prismatic cohomology admit logarithmic Gysin sequences.
