    We investigate instantons on sine-cones over Sasaki-Einstein and 3-Sasakian manifolds. It is shown that these conical Einstein manifolds are Kähler with torsion (KT) manifolds admitting Hermitian connections with totally ...
  • Lechtenfeld, Olaf; Popov, Alexander D. (Melville, NY : AIP Publishing, 2012)
    We consider the six-sphere S6 = G2/SU(3) and its twistor space Z=G2/U(2) associated with the SU(3)-structure on S6. It is shown that a Hermitian Yang-Mills connection (instanton) on a smooth vector bundle over S6 is ...

    We revisit the problem of constructing instantons on ADE orbifolds R4/Γ and point out some subtle relations with the complex structure on the orbifold. We consider generalized instanton equations on R4/Γ which are BPS ...
  • Ivanova, T.A.; Lechtenfeld, Olaf; Popov, Alexander D. (College Park, MD : American Physical Society, 2017)
    We consider pure SU(2) Yang-Mills theory on four-dimensional de Sitter space dS4 and construct a smooth and spatially homogeneous magnetic solution to the Yang-Mills equations. Slicing dS4 as R×S3, via an SU(2)-equivariant ...
  • Popov, Alexander D. (College Park, MD : American Physical Society, 2015)
    We consider Yang-Mills theory with a matrix gauge group G on a direct product manifold M=Σ2×H2, where Σ2 is a two-dimensional Lorentzian manifold and H2 is a two-dimensional open disc with the boundary S1=∂H2. The ...
  • Lechtenfeld, Olaf; Popov, Alexander D. (Melville, NY : AIP Publishing, 2016)
    We consider Yang-Mills theory with N = 1 super-translation group in eleven auxiliary dimensions as the structure group. The gauge theory is defined on a direct product manifold Σ3 × S1, where Σ3 is a three-dimensional ...
  • Lechtenfeld, Olaf; Popov, Alexander D. (Amsterdam : Elsevier, 2016)
    It was pointed out by Shifman and Yung that the critical superstring on X10=R4×Y6, where Y6 is the resolved conifold, appears as an effective theory for a U(2) Yang–Mills–Higgs system with four fundamental Higgs scalars ...
