Selected writings

Relation of Niemeier lattices to heterotic string theory:

• Wolfgang Lerche, Dieter Lüst, Adrian Norbert Schellekens, Ten-dimensional heterotic strings from Niemeier lattices, Physics Letters B 181 1–2 (1986) 71-75 [doi:10.1016/0370-2693(86)91257-8, inspire:233203]

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”, then also called the elliptic genus/Witten genus) and relation to Green-Schwarz anomaly cancellation:

• Wolfgang Lerche, Bengt Nilsson, A. N. Schellekens, Heterotic string-loop calculation of the anomaly cancelling term, Nuclear Physics B Volume 289, 1987, Pages 609-627 (doi:10.1016/0550-3213(87)90397-X)

• Wolfgang Lerche, Bengt Nilsson, A. N. Schellekens, Nicholas P. Warner, Anomaly cancelling terms from the elliptic genus, Nuclear Physics B Volume 299, Issue 1, 28 March 1988, Pages 91-116 (doi:10.1016/0550-3213(88)90468-3)

On the duality between F-theory and heterotic string theory:

• Wolfgang Lerche, On the Heterotic/F-Theory Duality in Eight Dimensions, In: Baulieu L., Green M., Picco M., Windey P. (eds.) Progress in String Theory and M-Theory, NATO Science Series (Series C: Mathematical and Physical Sciences), vol 564. Springer 2001 (arXiv:hep-th/9910207, doi:10.1007/978-94-010-0852-5_2)

On D-branes at an ADE-singularity and their open string worldsheet 2d CFTs (see also here):

• Wolfgang Lerche, Carsten Andrew Lütken, Christoph Schweigert, D-Branes on ALE Spaces and the ADE Classification of Conformal Field Theories, Nucl.Phys. B 622 (2002) 269-278 (doi:10.1016/S0550-3213%2801%2900613-7, arXiv:hep-th/0006247)

On how this $\widehat{\mathfrak{su}(2)}^{\kappa-2}$-CFT encodes the BPS states of $SU(\kappa)$-SYM on D3-branes transverse to the singularity:

• Wolfgang Lerche, On a Boundary CFT Description of Nonperturbative $\mathcal{N} = 2$ Yang-Mills Theory (arXiv:hep-th/0006100)
