(14.05.) de Sitter in the String Landscape

I argue that four-dimensional effective field theory descriptions with de Sitter isometries could be allowed in the presence of time-dependent internal degrees of freedom in type IIB string landscape. Moduli stabilization and time-independent Newton constants are possible in such backgrounds. However once the time-dependences are switched off, there appear no possibilities of effective field theory descriptions.
