How to show a map is injective
WebApr 12, 2024 · An unusual part of the battle will be on Apep's 2nd battle phase where you will need to protect the Dendro Dragon from those slime monsters that are moving towards its core. This is to prevent the Dragon to regain its illness (revive). On its third battle phase, it will unleash a powerful attack that will change its appearance and the environment. WebThis is only true if the codomain has the same dimension as the domain. For instance, obviously there are linear maps that are injections and aren't surjections from k to k 2. I'm pretty sure the definition is just using the notation B = F [A] to indicate that the map is surjective. Continue this thread

Web1 in every column, then A is injective. If A red has a column without a leading 1 in it, then A is not injective. Invertible maps If a map is both injective and surjective, it is called invertible. This means, for every v in R‘, there is exactly one solution to Au = v. So we can make a map back in the other direction, taking v to u.
