Center node: "deterministic worst case dynamic connectivity simpler and faster"
  Abstract: We present a deterministic dynamic connectivity data structure for undirected graphs with worst-case update time $O(\sqrt{n}/w^{1/4})$ and constant query time, where $w = \Omega(\log n)$ is the word size. This bound improves on the previous best deterministic worst-case algorithm of Frederickson (STOC, 1983) and Eppstein Galil, Italiano, and Nissenzweig (J. ACM, 1997), having update time $O(\sqrt{n})$. All known faster dynamic connectivity algorithms are either randomized, or have amortized updates, or both.

Connected through hyperedge HE-1 (induced by source paper "an improved randomized data structure for dynamic graph connectivity"):
  with members:
    - "dynamic graph connectivity with improved worst case update time and sublinear space"

Connected through hyperedge HE-2 (induced by source paper "optimal decremental connectivity in planar graphs"):
  with members:
    - "structured recursive separator decompositions for planar graphs in linear time"
    - "faster deterministic fully dynamic graph connectivity"
    - "logarithmic lower bounds in the cell probe model"
