On solutions of IHPT equations on tangent bundles with the metric II + III

The main purpose of the present paper is to determine the most general IHPT (Infinitesimal Holomorphically Projective Transformation) on T(Mn)T(Mn) with respect to a Levi-Civita connection of the metric II+III and adapted almost complex structure. Moreover, if T(Mn)T(Mn) admits a non-affine infinitesimal holomorphically projective transformation, then MnMn and T(Mn)T(Mn) are locally flat.
