Hello! I hope I've posted this in the correct section...(adsbygoogle = window.adsbygoogle || []).push({});

I'm a 3rd year undergraduate and we're currently studying Vector Spaces (in QM) and I just don't understand what injective (one-to-one) and surjective (onto) mean? As a result I have no idea what an isomorphism is!

I realise this is probably a very simple question, but I'm just struggling so much with the course!

Cheers, Samantha
