  • Adapting the range of validity for the Carleman linearization 
    Weber, Harry; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2016)
    In this contribution, the limitations of the Carleman linearization approach are presented and discussed. The Carleman linearization transforms an ordinary nonlinear differential equation into an infinite system of linear ...
  • An extended Hamilton principle as unifying theory for coupled problems and dissipative microstructure evolution 
    Junker, Philipp; Balzani, Daniel (Berlin ; Heidelberg : Springer, 2021)
    An established strategy for material modeling is provided by energy-based principles such that evolution equations in terms of ordinary differential equations can be derived. However, there exist a variety of material ...
  • Modeling and simulation aspects of AC machines 
    Popp, Michael; Laza, Patrick; Mathis, Wolfgang (Warsaw : De Gruyter Open Ltd, 2016)
    In the field of power and drive systems, electrical AC machines are mostly modeled using a set of explicit ordinary differential equations in a state space representation. It is shown, that by using other equation types ...
  • Pure Yang–Mills solutions on dS 4 
    Ivanova, Tatiana A.; Lechtenfeld, Olaf; Popov, Alexander D. (Trieste : Sissa Medialab Srl, 2017)
    We consider pure SU(2) Yang–Mills theory on four-dimensional de Sitter space dS 4 and construct smooth and spatially homogeneous classical Yang–Mills fields. Slicing dS 4 as ℝ×S 3 , via an SU(2)-equivariant ansatz we reduce ...
  • Solutions to Yang-Mills Equations on Four-Dimensional de Sitter Space 
    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 ...
  • String theories as the adiabatic limit of Yang-Mills theory 
    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 ...
  • Supermembrane limit of Yang-Mills theory 
    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 ...
  • Superstring limit of Yang-Mills theories 
    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 ...
