Nonperturbative low-energy effective action of the universal hypermultiplet
Sergei V. Ketov
The non-perturbative (D-instanton corrected) low-energy effective action of the universal hypermultiplet in the type-IIA string theory compactified on a Calabi-Yau threefold is cal…
D-instantons and universal hypermultiplet
Sergei V. Ketov
Quantum non-perturbative geometry of the universal hypermultiplet is investigated. We consider the simple case when the D-instantons, originating from the Calabi-Yau wrapped D2-bra…
Engineering a bosonic AdS/CFT correspondence
Sergei V. Ketov, Thorsten Leonhardt, Werner Rühl
We search for a possible bosonic (i.e. non-supersymmetric) string/gauge theory correspondence by using IIB and 0B strings as a guide. Our construction is based on the low-energy bo…
Many faces of Born-Infeld theory
Sergei V. Ketov
Born-Infeld theory is the non-linear generalization of Maxwell electrodynamics. It naturally arises as the low-energy effective action of open strings, and it is also part of the w…
Why do we need supersymmetry?
Sergei V. Ketov
These short (personal) notes appeared as the result of my attempt to address the question raised in the title.
Holographic duality, supersymmetry, and Painleve equation
Sergei V. Ketov
An example of the holographic correspondence between 2d, N=2 quantum field theories and classical 4d, N=2 supergravity theories is found. The constraints on the target space geomet…
