If you have a question about this talk, please contact webseminars. Mathematical, Foundational and Computational Aspects of the Higher Infinite We prove that the Semi-Stationary Reflection Principle, together with the negation of the Continuum Hypothesis, implies that $omega_2$ has the Strong Tree Property. Also, we show that SSR implies the negation of $Box(lambda, omega)$ for all regular cardinals $lambdageqomega_2$. This is a joint work with Liuzhen Wu.
