Abstract: Please Note. This abstract contains mathematical formulae which cannot be represented here. We consider natural Laplace operators on random recursive affine nested fractals based on the Sierpinski gasket and prove an analogue of Weyl's classical result on their eigenvalue asymptotics. The eigenvalue counting function N ( ) is shown to be of order ds/2 as where we can explicitly compute the spectral dimension ds. Moreover the limit N ( ) -ds /2 will typically exist and can be expressed as a deterministic constant multiplied by a random variable. This random variable is a power of the limiting random variable in a suitable general branching process and has an interpretation as the volume of the fractal.
