New Large (n, r)-arcs in PG(2, q)

An $(n, r)$-arc is a set of $n$ points of a projective plane such that some $r$, but no $r+1$ of them, are collinear. The maximum size of an $(n, r)$-arc in  $PG(2, q)$ is denoted by $m_r(2,q)$.  In this paper we present  a new $(184,12)$-arc in PG$(2,17),$  a new $(244,14)$-arc and a new $(267,15$)-arc in $PG(2,19).$

^ d jw0j (w0) + ^ d jw1j (w1) 2 + E(jwj + 1) = d 0 (w0) + d 0 (w1) 2 so d 0 obeys the average law (without conservation). Proof.[of Theorem 19] Note the d 0 constructed in Theorem 18 is generally not conservative. We will parallel Theorem 4, by constructing a slothful two-sided quasipolynomially precise cover. The construction of a conservative cover from a slothful cover preserves two-sided qu...

LINES TANGENT TO 2 n − 2 SPHERES IN R n

We show that for n ≥ 3 there are 3·2 n−1 complex common tangent lines to 2n − 2 general spheres in R n and that there is a choice of spheres with all common tangents real.
