Hello everyone, I really need your help to identify a caracter in the following equation.

What is the I? I assume that is some kind of vector because it is bold, but what is its name and application?

Since now, thank you!

Thank you Dave! With your answer, I could search about tensors and I saw that it makes total sense!
