A decreasing filtration by supports \\phi : Z -> Spec(R) satisfies the weak Cousin condition if for any integer i \\in Z, the set \\phi(i) contains all the inmediate generalizations of each point in \\phi(i+1). Every t-structure on D^b_fg(R) (equivalently, on D^-_fg(R)) is induced by complactly generated t-structures on D(R) whose associated filtrations by supports satisfy the weak Cousin condition.
