Linear Operators. A linear operator T is an operator such that the domain D(T) of T is a vector space and the range R(T) lies in a vector space over the same field,for all x, y ? D(T) and scalars a,T(x y) = Tx TyT(ax)=aTxT: D(T) ? R(T)T(ax

2. Linear Operators A linear operator T is an operator such that
the domain D(T) of T is a vector space and the range R(T) lies in a vector space over the same field,
for all x, y ? D(T) and scalars a,
T(x+y) = Tx + Ty
T(ax)=aTx
T: D(T) ? R(T)
T(ax+ßy)=aTx+ßTy
Null space of T is the set of all x ? D(T) such that Tx=0
