Cyclic Lagrangian Submanifolds and Lagrangian Fibrations
Tokyo Journal of Mathematics, 2005 Recall that a symplectic manifold \((M,\omega)\) is called prequantizable if there exists a nonnegative number \(\gamma_\omega\) such that the period group \(\Gamma_\omega= \{[\omega](A)= \int_A \omega: A\in H_2(M,\mathbb{Z})\}\subset \mathbb{R}\) is of the form \(\Gamma_\omega= \gamma_\omega\cdot\mathbb{Z}\).

Equation on the basis of one-dimensional chaotic dynamics
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013 Modified Klein–Gordon–Fock equations were obtained on the basis of one-dimensional chaotic dynamics and the original Lagrangians were found. The concepts of $m$-exponential map and groups with broken symmetry are introduced.

Lagrangians of Hypergraphs [PDF]
Combinatorics, Probability and Computing, 2002 How large can the Lagrangian of an r-graph with m edges be? Frankl and Füredi [1] conjectured that the r-graph of size m formed by taking the first m sets in the colex ordering of N(r) has the largest Lagrangian of all r-graphs of size m. We prove the first ‘interesting’ case of this conjecture, namely that the 3-graph with (t3) edges and ...

Applied Sciences, 2021 Numerical models are associated with uncertainties that can be reduced through data assimilation (DA). Lower costs have driven a recent tendency to use Lagrangian instruments such as drifters and floats to obtain information about water bodies.

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Two-Dimensional Hydrodynamics as a Class of Special Hamiltonian Systems
East European Journal of PhysicsThe paper defines a class of Hamiltonian systems whose phase flows are exact solutions of the two-dimensional hydrodynamics of an incompressible fluid. The properties of this class are considered.
