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. Informally, a flow may be viewed as a continuous motion of points over time. More … 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 $${\displaystyle \varphi :X\times \mathbb {R} \to X}$$ such that, for all x ∈ … 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 … See more • Abel equation • Iterated function • Schröder's equation • Infinite compositions of analytic functions See more Algebraic equation Let $${\displaystyle f:\mathbb {R} \to X}$$ be a time-dependent trajectory which is a bijective function, … See more Web流量计.
