It is a commonly held misconception that little research in the area of finite Desarguesian geometry is going on at present. While it is true that classical geometry as a discipline has been far lessâ€¦ (More)

In [11], a new bound for the number of points on an algebraic curve over a "nite "eld of odd order was obtained, and applied to improve previous bounds on the size of a complete arc not contained inâ€¦ (More)

The number N of rational points on an algebraic curve of genus g over a finite field F q satisfies the Hasse-Weil bound N â‰¤ q + 1 + 2g âˆš q. A curve that attains this bound is called maximal. With g 0â€¦ (More)

1] constructed complete (q2-q + l)-arcs in PG(2, q2), q > 3. One of the interesting properties of these arcs is the fact that they are fixed by a cyclic protective group of order q2 â€” q + 1. Weâ€¦ (More)

The nucleus of a Veronese variety is the intersection of all its osculating hyperplanes. Various authors have given necessary and sufficient conditions for the nucleus to be empty. We present anâ€¦ (More)

A new periodontal probing system has been developed which incorporates the advantages of constant probing force, precise electronic measurement to 0.1 mm and computer storage of the data. The systemâ€¦ (More)
