To be precise, f is apartialfunction of positive integers, being undefined for arguments greater than 3. ...

Query Answering for OWL-DL with Rules
... some of the expressive power of OWL-DL: they are restricted to universal quantification and lack negation in their basic form. To overcome the limitations of both approaches, OWL-DL was extended with rules in [11], but this extension is undecidable [11]. Intuitively, the undecidability is due to the ...

on unramified galois extensions of real quadratic
... From this point of view, for our purpose it is sufficient to find polynomials over Q with integral coefficients and square-free discriminants. This enables us to give examples easily. Now we give examples of real quadratic number fields with class number one having a strictly or weakly unramified ^- ...

On the least prime in certain arithmetic

The usual method used to nd large gaps between successive prime numbers is to construct a long sequence S of consecutive integers, each of which has a \small" prime factor (so tha ...
