摘要
Unique continuation of harmonic functions on RCD space is a long-standing open problem, with little known even in the setting of Alexandrov spaces. In this paper, we establish the weak unique continuation theorem for harmonic functions on RCD(K, 2) spaces and give a counterexample for strong unique continuation in the setting of RCD(K, N) space for any N >= 4 and any K is an element of R.
