Notations:
F denotes a field
V denotes a vector space over F
L(V) denotes a vector space whose members are linear operators from V to V itself and its field is F, then L(V) is an algebra where multiplication is composition of functions.
τ denotes a linear operator contained in L(V)
ι denotes the multiplicative identity of L(V)
Question:
Why is n2 + 1 vectors:
ι, τ, τ2, ... ,τn2
are linearly dependent in L(V)?
I wonder why, if these vectors are linear dependent, then one of them can be expressed as the linear combination of other vectors, but how?
Thanks for any help!
