In yesterday's lecture: I derived ¡­

In yesterday's lecture: I derived explicit formulas for the heat equation with Neumann boundary conditions. I also proved the energy estimate for the heat equation and used it to show uniqueness of solutions.

In the next lecture: I will derive stability and uniqueness by using maximum principles. I will describe explicit finite difference schemes for the heat equation.

For the group lesson this friday: Prepare exercises 3.5, 3.15, 3.16, 3.17, 3.18 and 3.20
