Matrix is Invertible: is this notation ok?

[kostoglotov]

Quick question, not even sure if I should post it here, but I can't think where else. If I wanted to write the short hand of A is an invertible matrix, would it be ok to just write

$$A \ \exists A^{-1}$$

?

That looks strange to me. It's better to just say that A is invertible. Trying to use short hand will just be confusing.

"$\det(A) \neq 0$"

I agree with FactChecker. Just say (in words) that A is invertible. Sometimes notation is not helpful in communicating clearly.
