Abstract/Summary: | |
The main purpose of the thesis is to compute the Hausdorff dimension of random fractals in general metric spaces. Such fractals are generated by random recursive constructions with finite “memory”. I study two different random models. Each of these models has the same underlying non-random Cantor type recursive construction, but they introduce random elements at each step quite differently.; In Chapter 2 I study random fractals generated by recursive constructions with independent scale coefficients whose distribution depends on several previous steps. The Hausdorff dimension is computed using a non-random linear operator associated with the construction and some martingale technique.; In Chapter 3 I study random fractals generated by recursive constructions with different, stationary random mechanism. The computation of Hausdorff dimension uses tools of the Ergodic Theory and Statistical Mechanics. |
