摘要
We introduce the notions of arithmetic Fontaine-Faltings module and arithmetic periodic Higgs bundle. As an example, we speculate there is one to one correspondence between the set of PGL_2 motivic local systems on the projective line minus 4 points and the set of torsion points on the associated elliptic curve via arithmetic period Higgs bundles and a proposed arithmetic Simpson correspondence. This is a joint project with R.R. Sun and J.B. Yang
