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.

On the off-shell superfield Lagrangian formulation of 4D, N=1 supersymmetric infinite spin theory
Physics Letters B, 2022 We develop a complete off-shell Lagrangian description of the free 4D,N=1 supersymmetric theory of infinite spin. Bosonic and fermionic fields are formulated in terms of spin-tensor fields with dotted and undotted indices.

Mean Curvature Flows of Lagrangian Submanifolds with Convex Potentials
, 2002 This article studies the mean curvature flow of Lagrangian submanifolds. In particular, we prove the following global existence and convergence theorem: if the potential function of a Lagrangian graph in T^{2n} is convex, then the flow exists for all ...

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Unfolding a Hidden Lagrangian Structure of a Class of Evolution Equations
Axioms, 2022 It is shown that a simple modification of the standard Lagrangian underlying the dynamics of Newtonian lattices enables one to infer the hidden Lagrangian structure of certain classes of first order in time evolution equations which lack the conventional

A hybrid Eulerian–Lagrangian numerical scheme for solving prognostic equations in fluid dynamics [PDF]
Geoscientific Model Development, 2013 A new hybrid Eulerian–Lagrangian numerical scheme (HEL) for solving prognostic equations in fluid dynamics is proposed. The basic idea is to use an Eulerian as well as a fully Lagrangian representation of all prognostic variables.

Conic lagrangian singularities
Topology and its Applications, 1998 By definition, a complex analytic manifold is called conic if it is endowed with a proper free \({\mathbb C}^\ast\)-action. A conic map is a \({\mathbb C}^\ast\)-equivariant map of conic manifolds. Modifying considerations of [\textit{V. I. Arnold}, \textit{S. M. Gusejn-Zade} and \textit{A. N. Varchenko}, `Singularities of differentiable maps.
