Hi, just wondering what this thing means.

$$

E^2_k|_{k=k_{res}}

$$

Just the k=k(res) after the vertical line. There is no definition in the textbook but in math does that mean from K=K(res) to something that can be dependent on a function or a situation?

Like definite integrals answer $$x|^3_2=3-2=1$$
