We present a unified translation of LTL formulas into deterministic Rabin automata, limit-deterministic Büchi automata, and nondeterministic Büchi automata. The translations yield automata of asymptotically optimal size (double or single exponential, respectively). All three translations are derived from one single Master Theorem of purely logical nature. The Master Theorem decomposes the language of a formula into a positive boolean combination of languages that can be translated into omega-automata by elementary means. In particular, the breakpoint, Safra, and ranking constructions used in other translations are not needed.

Joint work with Jan Kretinsky and Salomon Sickert.
