1. Flag manifold σ -models: The 1N -expansion and the anomaly two-form / Bykov, Dmitri
We construct a gauged linear sigma-model representation and develop a 1N -expansion for flag manifold σ -models previously proposed by the author. [...]

2. Complex structure-induced deformations of σ -models / Bykov, Dmitri
We describe a deformation of the principal chiral model (with an evendimensional target space G ) by a B -field proportional to the Kähler form on the target space. [...]

3. Complex structures and zero-curvature equations for σ -models / Bykov, Dmitri
We construct zero-curvature representations for the equations of motion of a class of σ -models with complex homogeneous target spaces, not necessarily symmetric. [...]

4. Classical solutions of a flag manifold σ -model / Bykov, Dmitri
We study a σ -model with target space the flag manifold U(3)U(1)3 and a nonzero Kalb–Ramond field, which is specified by a choice of integrable complex structure on the target space. [...]

5. Integrable properties of σ -models with non-symmetric target spaces / Bykov, Dmitri
It is well known that σ -models with symmetric target spaces are classically integrable. [...]
