DESCRIPTION:We prove that the Semi-Stationary Reflection Principle\, toget
 her with the negation of the Continuum Hypothesis\, implies that $omega_2$
  has the Strong Tree Property. Also\, we show that SSR implies the negatio
 n of $Box(lambda\, omega)$ for all regular cardinals $lambdageqomega_2$. T
 his is a joint work with Liuzhen Wu.\n
