I have a homework problem discussing the heat equation, and I have two questions about notation that I could not figure out through google searching:
[itex]L^1(ℝ)[/itex] as in a function [itex]g\in C^1(ℝ)\cap L^1(ℝ)[/itex]
[itex]||u(\bullet ,t)||_{L^∞}[/itex]
The bullet in the second expression is actually a single dot at that height, but I could not find the latex symbol for it. I initially thought it was a limit as [itex]x\rightarrow\infty[/itex] but that is incorrect.
