Abstract
This paper mainly studies one-dimensional mean-field backward stochastic differential equations (MFBSDEs) when their coefficient is uniformly continuous in
, independent of
and non-decreasing in
. The existence of the solution of this kind MFBSDEs has been well studied. The uniqueness of the solution of MFBSDE is proved when
is also independent of
. Moreover, MFBSDE with coefficient
, in which
is a real number, has non-unique solutions, and it’s at most countable.
