We show a fully dynamic algorithm for maintaining $(1+\epsilon)$-approximate size of maximum matching of the graph with n vertices and m edges using $m^{0.5-\Omega_{\epsilon}(1)}$ update time. This is the first polynomial improvement over the long-standing $O(n)$ update time, which can be trivially obtained by periodic recomputation. Thus, we resolve the value version of a major open question of the dynamic graph algorithms literature (see, e.g., [Gupta and Peng FOCS’13], [Bernstein and Stein SODA’16], [Behnezhad and Khanna SODA’22]). Our key technical component is the first sublinear algorithm for $(1, \epsilon n)$-approximate maximum matching with sublinear running time on dense graphs. All previous algorithms suffered a multiplicative approximation factor of at least 1.499 or assumed that the graph has a very small maximum degree.
