摘要
The spherical variants of multiscale methods - Voronoi tesselation, minimal spanning tree, and multifractal analysis - are used to test the angular distributions of three subgroups of gamma-ray bursts (GRBs) collected in BATSE Gamma-Ray Burst Catalog. They verify the isotropy of the sky distribution of gamma-ray bursts. The short - in some tests also the intermediate - subclass exhibit anisotropic distribution. The distribution of long subclass seems to be isotropic.
