Summary: Let \(V\) be the ring of integers of a finite extension of \(\mathbb Q_p\) and let \(X\) be a proper curve over \(V\) with semistable special fiber and smooth generic fiber. In this article we explicitly describe the Frobenius and monodromy operators on the log crystalline cohomology of \(X\) with values in a regular \(\log F\)-isocrystal in terms of \(p\)-adic integration. We have a version for open curves and as an application we prove that two differently defined \(\mathcal L\)-invariants, attached to a split multiplicative at \(p\) new elliptic eigenform, are equal.
