Flow of vector field
The idea of a vector flow, that is, the flow determined by a vector field, occurs in the areas of differential topology, Riemannian geometry and Lie groups. Specific examples of vector flows include the geodesic flow, the Hamiltonian flow, the Ricci flow, the mean curvature flow, and Anosov flows. See more In mathematics, a flow formalizes the idea of the motion of particles in a fluid. Flows are ubiquitous in science, including engineering and physics. The notion of flow is basic to the study of ordinary differential equations. … See more A flow on a set X is a group action of the additive group of real numbers on X. More explicitly, a flow is a mapping $${\displaystyle \varphi :X\times \mathbb {R} \to X}$$ See more Algebraic equation Let $${\displaystyle f:\mathbb {R} \to X}$$ be a time-dependent trajectory which is a bijective function, … See more Given x in X, the set $${\displaystyle \{\varphi (x,t):t\in \mathbb {R} \}}$$ is called the orbit of x under φ. Informally, it may be regarded as the trajectory of a particle that was initially positioned at x. If the flow is generated by a vector field, then its orbits are the images of its See more • Abel equation • Iterated function • Schröder's equation See more WebVector fields can usefully be thought of as representing the velocity of a moving flow in space, and this physical intuition leads to notions such as the divergence (which represents the rate of change of volume of a flow) …

There is a unique maximal flow D → M whose infinitesimal generator is V. Here D ⊆ R × M is the flow domain. For each p ∈ M the map Dp → M is the unique maximal integral curve of V starting at p. A global flow is one whose flow domain is all of R × M. Global flows define smooth actions of R … In mathematics, a flow formalizes the idea of the motion of particles in a fluid. Flows are ubiquitous in science, including engineering and physics. The notion of flow is basic to the study of ordinary differential equations.
