Seminar on Algebra, Geometry and Physics Blowup equations as the functional equations for the Nekrasov partition function of 4-dimensional gauge theory was proposed by Nakajima-Yoshioka in 2003. Certain K-theoretic versions were soon later found by Göttsche, Nakajima and Yoshioka. I will talk about two further generalizations found in recent three years, an elliptic version from the viewpoint of gauge theory and a most general version from the viewpoint of topological string theory on local Calabi-Yau threefolds. These equations can be used to solve the elliptic genera of certain 6d gauge theories and the refined BPS invariants of local Calabi-Yau.
