Since all fields are discretized to at least second order, the geometry shape order will thus automatically also be second order.
你能解释一下你刚刚说的吗,虽然眼下我还不知道二阶逻辑是什么。
I would ask you to explain why that was true, but at this point I don't even know what second-order logic is.
定义:在数学中,Hessian矩阵或者Hessian是一个多变量实值函数的二阶偏导数组成的方阵。

学术知识是一种二阶形式的知识,是通过推理和证据得出的抽象、概括的知识。
Academic knowledge is a second-order form of knowledge that seeks abstractions and generalizations based on reasoning and evidence.
System F allows polymorphism by using universal quantification over all types; from a logical perspective it can describe all functions that are provably total in second-order logic.
In mathematical logic, predicate logic is the generic term for symbolic formal systems like first-order logic, second-order logic, many-sorted logic, or infinitary logic.
Independently of Larmor, also Lorentz(1899) extended his transformation for second order terms and noted a(mathematical) Time Dilation effect as well.
二阶张量是矩阵(2个指数)和三阶张量(3个指数),更高的称为高阶张量(超过3个指数)。
A second order tensor is a matrix(2 indices) and third-order tensors(3 indices) and higher are called higher-order tensors(more than 3 indices).
事实上,它完全由第一基本形式决定并且可以用第一基本形式及其一阶和二阶偏导数表达。
In fact, it can be found given the full knowledge of the first fundamental form and expressed via the first fundamental form and its partial derivatives of first and second order.
The system λ Π 2{\displaystyle\lambda\Pi 2} of second order dependent types is obtained from λ Π{\displaystyle\lambda\Pi} by allowing quantification over type constructors.
