This is my first post on StackExchange. I had a quick question about notation (appearing in research literature) that I was unable to find by repeated searches, and I was hoping that someone would be able to help.
I am dealing with finite fields $\mathbb{F}_q$, where $q$ is a power of a prime $p$, and a multiplicative character $\chi: \mathbb{F}_q^* \to \mathbb{C}^*$. I want to consider a character satisfying $\chi(\mathbb{F}_q^*)=1$, notation I am not familiar with. If anyone could help me define this or direct me to a source that can, it would be much appreciated.
Thank you very much!
Edit: Please see the comments below for the context of the notation.
