Vector Space of n-Tuples

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z overview

Let $ K$ be a field. Then the $ n$-tuple,

$\displaystyle a = (a_1,\ldots,a_n)^{\operatorname t},\quad a_i\in K\, ,

endowed with addition and multiplication by components, form the $ K$-vector space $ K^n$, where addition and multiplication by components mean:

$\displaystyle (a_1,\ldots,a_n)^{\operatorname t}+ (b_1,\ldots,b_n)^{\operatorname t}=
(a_1+b_1,\ldots,a_n+b_n)^{\operatorname t}


$\displaystyle \lambda (a_1,\ldots,a_n)^{\operatorname t}=
(\lambda a_1,\ldots,\lambda a_n)^{\operatorname t}

for $ a_i,b_i,\lambda\in K$.
