Linear Transformations: Projection

Projection Definition for Engineering Maths or Mathematics - Linear Transformations: Projection

Projection


Definition

Let V be a vector space and W1 and W2 be subspaces of V such that V=W1  W2. The function T: V→ V defined by T (x)=x1 where x=x1+x2 with x1 W1 and x2 W2 is called the projection of V on W1 or the projection on W1 along W2.


Definition

Let V be a vector space and let T: V→V be linear. A subspace W of V is said to be T−invariant if T (x) W for every x W, (ie) T (W)  W. If W is T−invariant, we define the restriction of T on W to be the function Tw: W  W defined by

Tw(x)=T(x) for all x W.
