The phase behavior of confined nematogens is studied using the Lebwohl-Lasher model. For
three dimensional systems the model is known to exhibit a discontinuous nematic-isotropic phase
transition, whereas the corresponding two dimensional systems apparently show a continuous
Berezinskii-Kosterlitz-Thouless like transition. In this paper we study the phase transitions of the
Lebwohl-Lasher model when confined between planar slits of different widths in order to establish
the behavior of intermediate situations between the pure planar model and the three-dimensional
system, and compare with previous estimates for the critical thickness, i.e. the slit width at which
the transition switches from continuous to discontinuous.
