I am reading a paper about the spreading of something and the author added a formula to sum it up. My problem is, that I never saw a formula in that way of design. I got what the variables mean, but I do not get how to read that. Is the curly bracket meaning, that it is a group of formulas and the variables on the right are dependencies?
Thanks a lot!
The curly brackets mean that it is a piecewise function. Essentially, a piecewise function is a function made out of other functions. You know when to apply each function inside the bracket by looking at the interval provided to the right of each function.
Also, $\exp(x)$ is another way of writing $e^x$
