Die Eigenschaft von Ramsey wird in der reversen Mathematik genutzt, um die Stärke von Teilsystemen der Zahlentheorie der schwachen zweiten Stufe zu vergleichen. Wir zeigen, dass ein Teilsystem, dessen Stärke durch autonom iterierte Ramseyness bestimmt wird, beweistheoretisch äquivalent ist zu Pi-1-2-Komprehension. The property of Ramsey is used in reverse mathematics to compare the strength of subsystems of second order arithmetic. We show that a subsystem defined by autonomous iterated Ramseyness is prooftheoretically equivalent to Pi-1-2-comprehension
