Abstract
In the present paper, the (HM¢,S,T)-Cartan connections on pseudo-Finsler manifolds, introduced by A. Bejancu and H.R. Farran, are obtained by the natural almost complex structure arising from the nonlinear connection HM¢. We prove that the natural almost complex linear connection associated to a (HM¢,S,T)-Cartan connection is a metric linear connection with respect to the Sasaki metric G. Finally we give some conditions for (M¢,J,G) to be a Kähler manifold.

Key words: almost complex structure; Kähler and pseudo-Finsler manifolds; (HM¢,S,T)-Cartan connection.
