How Long are the Arms in DBM?

Area of Science:

• Physics
• Complex Systems
• Fractal Growth

Background:

• Diffusion Limited Aggregation (DLA) and Dielectric-Breakdown Models (DBM) are crucial for modeling natural phenomena.
• Existing knowledge on DLA and DBM, particularly Kesten's estimate on DLA growth, is limited.
• A need exists for generalized estimates applicable to DBMs.

Purpose of the Study:

• To generalize Kesten's estimate for Dielectric-Breakdown Models (DBM) in 2 and 3 dimensions.
• To provide a new analytical approach for understanding fractal growth phenomena.
• To offer a novel proof for Kesten's existing results in DLA.

Main Methods:

• Development of a novel mathematical approach distinct from Kesten's original methods.
• Application of the new method to derive generalized estimates for DBM growth.
• Analysis of the DBM parameter's influence on the obtained estimates.

Main Results:

• A generalized estimate for DBM growth in 2 and 3 dimensions was successfully proven.
• The new estimate is dependent on the DBM parameter.
• The derived estimates align with the best-known results for DLA.

Conclusions:

• The study provides a significant advancement in the theoretical understanding of DLA and DBM.
• The novel methodology offers a new perspective and proof for established results in fractal growth.
• This work deepens our comprehension of complex physical phenomena approximated by DLA and DBM.
