We present a new short combinatorial proof of the sufficiency part of the well-known Kuratowski's graph planarity criterion. The main steps are to prove that for a minor minimal non-planar graph G and any edge xy: (1) G-x-y does not contain θ-subgraph; (2) G-x-y is homeomorphic to the circle; (3)
In this note, w e give a short proof of a stronger version of the following theorem: Let G be a 2-connected graph of order n such that for any independent set {u, u , w}, then G is hamiltonian. 0 1996 John
It is often assumed in the facility location literature that functions of the type +i(z, y) =p,{(zj-z)\*+ (yi-y)a]R/s are twice differentiable. Here we point out that this is true only for certain values of K. Convexity proofs that are independent of the value of K are given. DIFFERENTIABILITY Consi
