Hi there, I have to solve the following problem: A semi-infinite body x<0 has thermal conductivity K_1 , density \rho_1 , and specific heat C_1. It is initially at temperature T_0. At time t=0, it is placed in thermal contact with the semi-infinite body x>0, which has parameters K_2 , \rho_2...

I don't think it is a typo. Omega is just a constant here, I think.

When trying to solve a problem I arrive at the following equation of motion / Hill equation: \frac{d^{2}y}{dx^2} + \frac{4 k_0}{m w^2} cos(2x)y = 0 There exists a value x_0 such that for all x>x_0 the motion is stable. I actually don't know what is meant by this 'stability'. Can...
