最常見/最基礎嗰啲應該都係你讀linear algebra嗰時已經見唔少
e.g. R^n, C^n, space of continuous functions on [a,b], space of continuously differentiable functions on [a,b], space of polynomials, space of polynomial of degree at most n etc.
其他唔同area會常見嘅vector space又唔一樣
例如
differential equations: 一條linear homogeneous equation嘅solution space
analysis: space of integrable functions on [a,b]
其他就唔詳細列了
唔常見例子:
On set of elements in R^2, define
(x,y) "+" (z,w) = (x+z, y+w+1)
a "‧" (x,y) = (ax, ay+a-1)
咁樣都會define到個vector space

Key word: functional analysis (可以話用analysis角度睇linear algebra, 呢度會明infinite dim d 性質同F^n 有幾唔同)
係algebra都會見到,module係fancy版linear algebra, d coefficient唔一定係RCQ呢d fields, 可以係matrices, integers, etc.

比kin li 屠殺完而家好掛住佢
btw出年ust fall sem新開math analysis
好期待新版本
