Stabilizing Decomposition of Multiparameter Modules

Explore the challenges and recent advancements in stabilizing decomposition of multiparameter modules in this 46-minute lecture by Håvard Bakke Bjerkevik. Delve into the complexities of multiparameter module decomposition, understanding why it is inherently unstable compared to one-parameter persistence modules. Discover why conventional approaches to establishing stability theories for multiparameter module decomposition often fall short. Learn about groundbreaking research that demonstrates the possibility of proving decomposition stability theorems despite these obstacles. If time permits, examine a conjecture that could potentially strengthen the main stability result for staircase decomposable modules, with implications for other areas of multipersistence. Gain insights from the speaker's arXiv preprint, which forms the basis of this talk presented for the Applied Algebraic Topology Network.
