If Q is a submodule of some other left R-module M, then there exists another submodule K of M such that M is the internal direct sum of Q and K, i.e. Q + K = M and Q ∩ K = {0}.; Any short exact sequence 0 →Q → M …

WebbInjektiv. En injektiv funktion. En anden injektiv funktion. En ikke-injektiv funktion. En afbildning er injektiv (eller en-til-en), hvis forskellige elementer i A giver forskellige funktionsværdier i B. Sagt mere stringent, φ er injektiv netop, når .
