Resumen

We extend the Fixed Scale Transformation (FST) method, developed for Laplacian fractal growth, to the case of aggregation phenomena based on diffusing particles following Levy-flight walk. We compute analytically the clusters fractal dimension for different values of the exponent governing the Levy-flight trajectories. The results obtained are in very good agreement with the numerical simulations and show analytically how the different screening effects present in the Levy-flight diffusion change the aggregates fractal dimension.
