What are the conditions for a linear transformation to be one to one?
- A linear transformation T: Rn ? Rm is called one to one (often written as 1 ? 1) if whenever ?x1 ? ?x2 it follows that : T(?x1) ? T(?x2) Equivalently, if T(?x1) = T(?x2), then ?x1 = ?x2. Thus, T is one to one if it never takes two different vectors to the same vector.

What is the simple rule for checking one to one in the case of linear transformations?
- A linear transformation T: Rn ? Rm is called one to one (often written as 1 ? 1) if whenever ?x1 ? ?x2 it follows that : T(?x1) ? T(?x2) Equivalently, if T(?x1) = T(?x2), then ?x1 = ?x2. Thus, T is one to one if it never takes two different vectors to the same vector.
What is a one-to-one linear transformation?
- Definition (Injective, One-to-One Linear Transformation). A linear transformation is said to be injective or one-to-one if provided that for all u 1 and u 1 in U, whenever T ( u 1) = T ( u 2), then we have u 1 = u 2. Proof. ( ?): If T is injective, then the nullity is zero.
