N ov 2 00 3 NATURALLY FULL FUNCTORS IN NATURE

We introduce and discuss the notion of naturally full func-tor. The definition is similar to the definition of separable functor: a naturally full functor is a functorial version of a full functor, while a separable functor is a functorial version of a faithful functor. We study general properties of naturally full functors. We also discuss when func-tors between module categories and between c...

We present a multiwavelength study of the environment of the unidentified X-ray/γ-ray sources IGR J18027−1455 and IGR J21247+5058, recently discovered by the IBIS/ISGRI instrument, onboard the INTEGRAL satellite. The main properties of the sources found inside their position error circles, give us clues about the nature of these high-energy sources.

We treat interpolation for various logics. In the full non-monotonic case, we connect the existence of interpolants to laws about abstract size, and to generalized Hamming relations. We also mention revision a la Parikh.
