Alias-Alibi?

Question

What does that phrase mean?

I probably should have given some context for the phrase. Anyways, it is coming from the sentence:

"There is alwayss an alias-alibi aspect of such transformations."

And this phrase is found in a section dealing with linear transformations in a tensor calculus book.

Answer 1

I don't know what the phrase means. Never heard of it. But "alias" means "known by another name" (like Jim Johnson is also kown as Bill Williams). "Alibi" means the plea of being somewhere else at the time of a commission of a wrong doing.

Answer 2

I dunno.

An alias is a fake name.
An alibi is hopefully not a fake reason why that person could never have committed this particular crime. An alibi just means you have proof that you could not have been at the scene of a crime while the crime was being committed.
