Abstract:	For the SOS model defined by the Hamiltonian $H(\phi ) = \frac{1}{2}\sum\nolimits_{\left\langle {x,x'} \right\rangle } {\left\| {\phi _x - \phi _{x'} } \right\| + h\sum\nolimits_x {\phi _x } }$ , where _x, _x,{1,2,...},h>0,x^d,d2 it is shown that in the low-temperature region an infinite sequence of first-order phase transitions takes place whenh»0 and the temperature is fixed.

Keywords:	SOS model layering transition entropic repulsion cluster expansion dominant ground states
