WebNeumann Boundary Conditions Robin Boundary Conditions Remarks At any given time, the average temperature in the bar is u(t) = 1 L Z L 0 u(x,t)dx. In the case of Neumann boundary conditions, one has u(t) = a 0 = f. That is, the average temperature is constant and is equal to the initial average temperature. Also in this case lim t→∞ u(x,t ... WebFeb 4, 2024 · In this paper, we give a probabilistic interpretation for solutions to the Neumann boundary problems for a class of semi-linear parabolic partial differential equations (PDEs for short) with singular non-linear divergence terms. This probabilistic approach leads to the study on a new class of backward stochastic differential equations … bohr model and rutherford model
