What is injective also known as?
Could you please explain to me what injective is commonly referred to as in the realm of mathematics? I've heard it mentioned in a few discussions but haven't quite grasped its alternative name. Could you clarify this concept for me, perhaps with a brief description of its significance in the field? It would be greatly appreciated if you could keep the explanation concise yet comprehensive, as I'm eager to understand this concept better. Thank you in advance for your assistance.
