A Weak Gravity Conjecture for Scalar Field Theories
... In action (9) we have set 8G = 1. By recovering G, one finds that the expansion parameter is not g but √gG . This accounts for the name “weak/strong gravity”. The calculation above tells us that kink solutions appear in weak gravity limit √gG ≫ 1 but disappear in strong gravity limit √gG ≪ 1. In the ...

Black-Body Radiation for Twist-Deformed Space
