Syntomic complexes and p-adic etale Tate twists

The primary goal of this paper is to identify syntomic complexes with the p-adic etale Tate twists of Geisser-Sato-Schneider on regular p-torsion-free schemes. Our methods apply naturally to a broader class of schemes that we call 'F-smooth'. The F-smoothness of regular schemes leads to new results on the absolute prismatic cohomology of regular schemes.
