Lagrangian pairs and Lagrangian orthogonal matroids
European Journal of Combinatorics, 2005 Represented Coxeter matroids of types $C_n$ and $D_n$, that is, symplectic and orthogonal matroids arising from totally isotropic subspaces of symplectic or (even-dimensional) orthogonal spaces, may also be represented in buildings of type $C_n$ and $D_n$, respectively.

Lagrangian Reduced Order Modeling Using Finite Time Lyapunov Exponents
Fluids, 2020 There are two main strategies for improving the projection-based reduced order model (ROM) accuracy—(i) improving the ROM, that is, adding new terms to the standard ROM; and (ii) improving the ROM basis, that is, constructing ROM bases that yield more ...

Physics Letters B, 2019 By including an additional self-dual three-form we construct a Lorentz invariant lagrangian for the abelian (2,0) tensor supermultiplet. The extra three-form is a supersymmetry singlet and decouples from the (2,0) tensor supermultiplet.

Routh Reduction by Stages [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2011 This paper deals with the Lagrangian analogue of symplectic or point reduction by stages. We develop Routh reduction as a reduction technique that preserves the Lagrangian nature of the dynamics.

Higgs Effective Lagrangian [PDF]
EPJ Web of Conferences, 2013 We present a short overview of the main aspects of the Higgs Effective Lagrangian. In particular we highlight a strategy to determine whether the electroweak symmetry breaking sector is controlled by a strong or a weak dynamics.

Formal Lagrangian Operad [PDF]
International Journal of Mathematics and Mathematical Sciences, 2010 Given a symplectic manifold M, we may define an operad structure on the the spaces Ok of the Lagrangian submanifolds of (M¯)k×M via symplectic reduction.

Milan Journal of Mathematics, 2022 AbstractWe review the theory of Lagrangian fibrations of hyperkähler manifolds as initiated by Matsushita. We also discuss more recent work of Shen–Yin and Harder–Li–Shen–Yin. Occasionally, we give alternative arguments and complement the discussion by additional observations.

Journal of Mathematical Physics, 2007 Searching for a Lagrangian may seem either a trivial endeavor or an impossible task. In this paper, we show that the Jacobi last multiplier associated with the Lie symmetries admitted by simple models of classical mechanics produces (too?) many Lagrangians in a simple way. We exemplify the method by such a classic as the simple harmonic oscillator, the

Freudenthal dual Lagrangians [PDF]
Classical and Quantum Gravity, 2013 The global U-dualities of extended supergravity have played a central role in differentiating the distinct classes of extremal black hole solutions. When the U-duality group satisfies certain algebraic conditions, as is the case for a broad class of supergravities, the extremal black holes enjoy a further symmetry known as Freudenthal duality (F ...
