| contents | Extending the Schramm--Loewner Evolution (SLE) to model branching structures while preserving conformal invariance and other stochastic properties remains a formidable research challenge. Unlike simple paths, branching structures, or trees, must be associated with discontinuous driving functions. Moreover, the driving function of a particular tree is not unique and depends on the order in which the branches are explored during the SLE process. This study investigates trees formed by nontrapping invasion percolation (NTIP) within the SLE framework. Three strategies for exploring a tree are employed: the invasion percolation process itself, Depth--First Search (DFS), and Breadth--First Search (BFS). We analyze the distributions of displacements of the Loewner driving functions and compute their spectral densities. Additionally, we investigate the inverse problem of deriving new traces from the driving functions, achieving a reasonably accurate reconstruction of the tree-like structures using the BFS and NTIP methods. Our results suggest the lack of conformal invariance in the exploration paths of the trees, as evidenced by the non-Brownian nature of the driving functions for the BFS and NTIP methods, and the inconsistency of the diffusion constants for the DFS method. |
