Ehresmann connectionsly lifted to a horizontal curve in .. An Ehresmann connection is good if every smooth curve in . has a global horizontal lift. For good connections we define the notions of parallel translation and holonomy.aggravate 发表于 2025-3-23 19:35:31
Wilfried Echterhoff,Detlev PoweleitPhysically, the . in the plane is described by a particle of unit mass acted upon by two linear springs of unit spring constant: one spring acts in the ..-direction and the other in the ..-direction. Mathematically, the . of the harmonic oscillator is Euclidean 2-space.orthodox 发表于 2025-3-24 01:13:09

In this chapter we discuss Hamiltonian systems with symmetry. By a symmetry of a Hamiltonian system (H, ., .) we mean a proper action of a Lie group G on a symplectic manifold (., .), which has a momentum mapping .: . → g*, and preserves the Hamiltonian ..cuticle 发表于 2025-3-24 18:35:14
