Abstract

We solve the Bonnet problem for surfaces in the homogeneous\hbox{$3$-manifolds} with a $4$-dimensional isometry group.More specifically, we show that a simply connectedreal-analytic surface in $\H^2\times \R$ or $\S^2\times \R$is uniquely determined pointwise by its metric and itsprincipal curvatures if and only if it is not a minimal ora properly helicoidal surface. In the remaining three typesof homogeneous $3$-manifolds, we show that except forconstant mean curvature surfaces and helicoidal surfaces,all simply connected real-analytic surfaces are pointwisedetermined by their metric and principal curvatures.
