Abstractо Te article is deбoted to te problem of olomorpicallд projectiбe transformations of locallд conformal Käler manifolds. It s Вort to be noted, tat J. Mikes and Z. RadАloБic aбe proбed tat a locallд conformal Käler manifold does not admit nite nontriбial olomorpicallд projectiбe mappings for a LeБi-CiБita connection. Earlier Вe ad also soвn tat a locallд conformal Käler manifold does not admit as Вell nontriбial in nitesimal olomorpicallд projectiбe transformations for te LeБi-CiБita connection. BАt since te WeДl connection de ned bд Lee form on a locallд conformal Käler manifold is F -connection, ence for te connection nontriбial in nitesimal olomorpicallд projectiбe transformations are possible. In te present paper Вe reвrite te sдstem of partial di erential eqаations for te LeБi-CiБita connection and introdаce so called in nitesimal conformal olomorpicallд projectiбe transformations. Tis alloвs Аs to obtain necessarд and sа cient conditions for a locallд conformal Käler manifold to aбe a groаp of in nitesimal conformal olomorpicallд projectiбe transformations. We also calcаlate te nаmber of parameters for sаc groаp, and describe tensor and non-tensor inбariants preserбed bд groаp tansformations. FinallД, Вe soв tat a Бector eld generating in nitesimal conformal olomorpicallд projectiбe transformations of a compact locallд conformal Käler manifold is contraбariant almost analдtic. і : і і, і, і, - - і. 9
