【 摘 要 】

Solar magnetic field structure in active regions is complicated for modeling. We construct by magnetogram data a special structure - discrete Morse-Smale complex. We perform simplification of complex using persistence pair elimination. Finally, we obtain a simplified complex that stores main topological features of the magnetogram data and neighbourhood relation between them.
