About the filtration of crystalline cohomology
Suppose $K$ is an finite unramified extension of $\mathbb Q_p$ with residue field $k$, and let $Y$ be an proper smooth variety defined over $k$. We know if $Y$ admits a proper smooth lifting $X/W(k)$ …

Is there a cohomology theory wider than crystalline?
We know crystalline cohomology is calculated by taking an inverse limit:
$$H_{cris}^i:=\varprojlim_nH_{cris}^i(X/W_n(k))$$
provided $X$ projective smooth over a perfect field $k$ of char $p$.
