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.

In the mathematical field of differential geometry, a geometric flow, also called a geometric evolution equation, is a type of partial differential equation for a geometric object such as a Riemannian metric or an embedding. It is not a term with a formal meaning, but is typically understood to refer to parabolic partial differential equations. Certain geometric flows arise as the gradient flow associated to a functional on a manifold which h… WebQ: math is not something you're terribly strong in 是什么意思？ A: It is an exaggerated phrase, which may mean, you’re not good in math . 查看更多回答 Webflow loss phenomena in the inlet swirling zone of the fan, a detailed experimental analysis is generally desired.
