## Selected writings

On the partition function of the superstring (heterotic string and type II string) as a modular form with values in the Chern character of the background field strengths (“character-valued partition function”, a little later called the elliptic genus/Witten genus) and relation to Green-Schwarz anomaly cancellation:

On supersymmetry and G-structure (notably Spin(7)-structure in M-theory on 8-manifolds):

On E-strings as M5-branes wrapped on a half K3?:

• J. A. Minahan, D. Nemeschansky, Nicholas Warner, Partition Functions for BPS States of the Non-Critical $E_8$ String, Adv. Theor. Math. Phys.1:167-183, 1998 (arXiv:hep-th/9707149)

• J. A. Minahan, D. Nemeschansky, Cumrun Vafa, Nicholas Warner, E-Strings and $N=4$ Topological Yang-Mills Theories, Nucl. Phys. B527 (1998) 581-623 (arXiv:hep-th/9802168)

On the Myers effect in M-theory for M2-branes polarizing into M5-branes of fuzzy 3-sphere-shape, with emphasis on the role of the Page charge/Hopf WZ term:

On non-uniqueness of black rings:

On (in-)stability of non-supersymmetric AdS vacua in string theory:
