Liouville type theorem for several generalized maps between Riemannian manifold

Abstract

In this paper, we mainly derive monotonicity formula of generalized map using conservation law, including $\phi$-$F$ harmonic map coupled with $\phi$-$F$ symphonic map with $m$ form and potential from metric measure space, $ p $ harmonic map with potential , $ V $ harmonic map with potential. As an corollary, we can derive Liouville theorem for these maps under some finite energy conditons. We also get Liouville type theorem for $\phi$-$F$ harmonic map coupled with $\phi$-$F$ symphonic map under asymptotic conditon on metric measure space. We also get Liouville theorem for $\phi$-$F$-$V$-harmonic maps in terms of the upper bound of Ricci curvature and the bound about sectional curvature on metric measure space. We also get Liouville theorem for $\phi$-$ F $-harmonic map without using monotonicity formula on metric measure space.
