Title: DE RHAM CRYSTALS ON THE PRISMATIC SITE OF OK
Abstract: Let Ok be a mixed characteristic complete discrete valuation ring with perfect residue field. We classify de Rham crystals over the (log-) prismatic site of Ok using certain log connections. By establishing a Sen-Fontaine theory for B representations over a Kummer tower, we further classify these crystals by (log-) nearly de Rham representations. In addition. we compare (log-) prismatic cohomology of these crystals with the corresponding de Rham cohomology and Galois cohomology. This is a joint work with Yu Min and Yupeng Wang.
