Title: Core-Halo Decomposition: Decentralizing Large-Scale Fixed-Point Problems
Abstract:
arXiv:2605.08681v1 Announce Type: cross Abstract: We study solving large-scale fixed-point equation \(x^\star=\bar F(x^\star)\) with decomposition. Standard strict decomposition assigns each agent a disjoint block and evaluates updates using only owned coordinates. For most operators, however, a block update may depend on variables outside the block. Truncating these dependencies by strict decomposition changes the mean operator and creates structural bias that cannot be removed by more samples,
