Graded epistemic justification

The adjective 'is justified' has all the hallmarks of a gradable adjective. But the relationship between gradable uses and straightforward predications of the form 'x is justified' has been underexplored by epistemologists. In this paper we undertake to do some ground clearing as a prelude to better understanding this relationship.

New double inequalities for g-frames in Hilbert [Formula: see text]-modules

In this work, we establish two types of double inequalities for g-frames in Hilbert [Formula: see text]-modules, which involve scalars [Formula: see text] and [Formula: see text] respectively. It is shown that the results we obtained can immediately lead to the existing corresponding results when taking [Formula: see text].
