Lift-independence problem in the $P$-adic Simpson correspondence for curves
Abstract
Let be a proper smooth rigid analytic variety over a complete algebraically closed field -adic field . Fix an continuation . Faltings (in the curve case) and Heuer showed that any lifting of over induces an equivalence bewteen the category of Higgs bundles on and the category of -bundles on . In this paper, we aim to study how the equivalence depends on the choice of such a lifting when is a curve of genus . More precisely, we call a Higgs bundle lift-independent if it always corresponds to the same -bundle under -adic Simpson correspondence with respect to any lifting and then we will show that (1) There exists some such that any semistable Hitchin-small Higgs bundle of rank is lift-independent. (2) There always exists a semistable Higgs bundle of degree with non-zero Higgs field that is lift-independent.
