Description
The relation between black hole event horizons and trapping horizons is investigated in a number of different situations. A notion of constant change is introduced that in certain situations allows the location of the event horizon to be identified. A modified definition is introduced to invariantly define the location of the trapping horizon under a conformal transformation. In this case the trapping horizon is not always a marginally outer trapped surface. A model is introduced that shows how trapping horizons can be expected to appear outside the event horizon before the black hole starts to evaporate.
