Freckled Instantons in Two and Four Dimensions
A. Losev, N. Nekrasov, S. Shatashvili
Field theory with instantons can be partially regularized by adding degrees of freedom at some scale. These extra degrees of freedom lead to the appearence of the new topological d…
An Orbifold of Type 0B Strings and Non-supersymmetric Gauge Theories
Igor R. Klebanov, Nikita A. Nekrasov, Samson L. Shatashvili
We study a ${\IZ}_2$ orbifold of Type 0B string theory by reflection of six of the coordinates (this theory may also be thought of as a ${\IZ}_4$ orbifold of Type IIB string theory…
Two-dimensional Conformal Field Theories on AdS_{2d+1} Backgrounds
Jan de Boer, Samson L. Shatashvili
Various exact two-dimensional conformal field theories with AdS_{2d+1} target space are constructed. These models can be solved using bosonization techniques. Some examples are pre…
On Non-Supersymmetric CFT in Four Dimensions
Nikita Nekrasov, Samson L. Shatashvili
We show that the theories on the self-dual D3-branes of Type 0 string theory are in the class of the previously considered tadpole-free orbifolds of $\mathcal{N} =…
