$V$ -变量Sierpinski垫片的谱渐近性

Spectral Asymptotics for $V$-variable Sierpinski Gaskets

U. Freiberg, B. M. Hambly, John E. Hutchinson

摘要:

$V$ -变量分形的家庭提供了一种手段,以前在文献中考虑的两个家庭的随机分形之间的插值;规模不规则分形($V=1$)和随机递归分形($V=\infty$)。考虑一类基于Sierpinski垫片的$V$ -变量仿射嵌套分形,其测度为一般测度.我们计算的谱指数的一般措施,并找到这些分形的谱维数。我们发现,$V$ -变量分形的光谱特性和对角热核估计更接近那些规模不规则分形,因为它是规模的波动,确定其行为,但也有影响的空间变异性。

英文摘要:

The family of $V$-variable fractals provides a means of interpolating between two families of random fractals previously considered in the literature; scale irregular fractals ($V=1$) and random recursive fractals ($V=\infty$). We consider a class of $V$-variable affine nested fractals based on the Sierpinski gasket with a general class of measures. We calculate the spectral exponent for a general measure and find the spectral dimension for these fractals. We show that the spectral properties and on-diagonal heat kernel estimates for $V$-variable fractals are closer to those of scale irregular fractals, in that it is the fluctuations in scale that determine their behaviour but that there are also effects of the spatial variability.
