3 Initial Value Problem for the Heat Equation 3.1 Derivation of the equations Suppose that a function urepresents the temperature at a point xon a rod. The value of this function will change with time tas the heat spreads over the length of the rod. Thus u= u(x;t) is a function of the spatial point xand the time t. Our rst objective is to derive a partial di erential equation satis ed by the

Chapter 5 Green Functions In this chapter we will study strategies for solving the inhomogeneous linear di erential equation Ly= f. The tool we use is the Green function, which is an integral kernel representing the inverse operator L1. Apart from their use in solving inhomogeneous equations, Green functions play an important role in many areas of physics. 5.1 Inhomogeneous linear equations We

38 Green's Function: Diffusion Equation The Green's function method to solve the general initial≠ boundary value problem for diffusion equations is given. The Markovian property of the free-spaceGreen'sfunction (= heat kernel) is the key to construct Feynman-Kacpath integral representation of Green'sfunctions. Key words: reciprocity, general solution formula, eigen≠ function expansion

The dual-phase-lag heat equation was used to generalize macroscopic model in treating the transient heat conduction in finite slabs irradiated by short pulse laser using Greenís function method by [8,9]. For powerful reviewing of construction of several Greenís functions for different boundary and initial condition of various physical equations, the reader is referred to [10].

The heat equation on an interval. Theorem Warwick Insite

The function above will satisfy the heat equation and the boundary condition of zero temperature on the ends of the bar. The problem with this solution is that it simply will not satisfy almost every possible initial condition we could possibly want to use.

Does a Green's Function exist for the heat equation for a

speci?c heat of the material and Plugging a function u = XT into the heat equation, we arrive at the equation XT0 ?kX00T = 0: Dividing this equation by kXT, we have T0 kT = X00 X = ?ā: for some constant ā. Therefore, if there exists a solution u(x;t) = X(x)T(t) of the heat equation, then T and X must satisfy the equations T0 kT = ?ā X00 X = ?ā for some constant ā. In
