F is a field V is a vector space of all polynomial functions from F to F T and D are linear operators T(f(x)) = xf(x) D(f(x)) = f '(x) so DT =/= TD === 以上我懂,我不懂的是隨後的敘述 === Even though the "multiplication" we have on L(V,V) is not commutative , it is nicely related to the vector space operations of L(V,V) 我覺得是我英文太爛XD 求前輩們開釋!!! -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 1.164.46.179 ※ 文章網址: https://www.ptt.cc/bbs/Math/M.1464488257.A.F64.html

(英文也不好 猜猜看) 雖然題目裡的乘法不像我們熟知

的乘法運算(3*2=6)一樣可交換,但仍然是個運算

可是小弟覺得是合成捏

也許因線性轉換能用矩陣表示 他才把合成叫做乘法吧
