Several formulas of paraholomorphic maps are established, and a result of Lichnerowicz type is obtained. The connection transformations which have the same system of paracontact-planar Legendre curves are characterized. Conformal changes of metrics which preserve geodesics (resp. paracontact-planar Legendre curves) are studied.eninfo:eu-repo/semantics/closedAccessParacontact structures on manifoldsLinear connectionGeodesicsPlanar curveHarmonic mapArticle42118519910.1007/s40840-017-0475-y2-s2.0-85058129796Q2WOS:000454648900012Q2
