... three points are collinear in a (non-degenerate) drawing of K n . Thus dn(K n ) equals the minimum number of distinct distances determined by n points in the plane with no three points collinear. ... other interesting graph families including: degree-3 graphs, degree-4 graphs, 2-degenerate graphs with bounded degree, graphs with bounded degree and bounded pathwidth. • As described in...

... spans n and contains no collinear vectors remains open. However we conjecture that the minimum is attained precisely for the following configurations. 1 If n is even, H contains n linearly independent ... that H spans 3 and contains no collinear vectors, simp(H)is minimal if and only if H is contained in two planes intersecting in H,andone of which is of size exactly 3. The minimal configur...

... b 1 (mod 2 α 1 ). Since k is even, b 1 − 1 is relatively prime to 2 α 1 . Combining this with the relations discussed in the m odd case and applying the Chinese Remainder Theorem results in q, q  relatively ... main theorem for T containing only reflections, we call this the reflection main theorem. We then generalize to all T ∈ D n m . 3 Preliminaries and the Main Lemma Before proving the...

... points, lines and flags) with |P| = v and |L| = b satisfying the following axioms: (1) each line is incident with k points; (2) each point is incident with r lines; (3) two distinct points are incident ... the configuration is realized with points and lines in the projective plane. The arrows indicate that the corresponding points are at in nity, together with the line through them. while th...
