...eal numbers κand µone can define a distribution N(κ,µ) on Mby Nx(κ,µ) := {Z∈TxM|R(X,Y)Z= κ(g(Y,Z)X−g(X,Z)Y) +µ(g(Y,Z)hX−g(X,Z)hY)}. The distribution N(κ,µ) is called the (κ,µ)-nullity distribution. In [17], the case when the Reeb vector field of a contact metric manifold belongs to the (κ,µ)-nullity distribution was considered. A few years later, the almost coK¨ahler case was also considered ([69]). Thu...
