Good evening,
I have a small question: I am currently writing my master's thesis in mathematics, and I have a lot of equations full of estimates like $\|\cdots\|_1 \leq C \|\cdots\|_2$ where some constants get involved, which are ultimately meaningless, since its just about having an estimate for the norms.
Instead of introducing numerous constants like $C_1, C_2, ...$, I have seen some papers/ scripts always use the same letter and write something like "with the constant $C$ possibly changing". Although I think this is sometimes bad for understanding certain steps, I wonder if I should implement this...
So, my question boils down to: Is something like this considered bad style or sloppy writing?
