Basically, I would like to know which of the above is correct, and in what type of context.
From what I understand, the difference between characterisation and characterization might be that one of them is used in American English and the other in British English, but what about charactarisation? Is that written incorrectly?
I just found charactarisation in the title of a thesis, and I find it difficult to believe that they may have made a mistake in such an obvious place as the title. Maybe it has a different meaning? The title was this:
Charactarisation of submillimeter galaxies in the field of a protocluster around the high-redshift radio galaxy MRC1138-262
Is that correct, and if so, does it mean something specific?
