On the extension of bipartite to parity graphs

By using the new characterization, the following algorithmic results have been achieved: a linear time algorithm that solves the recognition problem, a linear time algorithm that

Size of a Futures Contract

• Similar to futures options except that what is delivered is a forward contract with a delivery price equal to the option’s strike price.. – Exercising a call forward option results

Size of a Futures Contract

• It works as if the call writer delivered a futures contract to the option holder and paid the holder the prevailing futures price minus the strike price.. • It works as if the

Strong chromatic index of planar graphs with large girth

∆ ≥ 7 is strong 3∆-edge-colorable: every planar graph G with maximum degree at least 7 is properly ∆-edge-colorable [22]; moreover if the girth of G is at least 7, then H i is
