I am slightly confused by the use of open vs closed interval for denoting the time-interval of the heat equation.
For example in lecture 27 (https://www.math.colostate.edu/~bangerth/videos.676.27.html), both the video lecture and the slides seem to convey that the PDE holds for the closed interval [0,t]. However, the step-26 tutorial page denotes the same pde as being valid only in the open interval (0,t). I acknowledge that this is a technical subtlety and may not change the results or code, but which one is more mathematically correct (closed-interval or open-interval)?
