Problem 1 Partitions of the product of three chains. Proposed by Shahriar Shahriari. Correspondent: Shahriar Shahriari Department of Mathematics, Pomona College, USA [email protected] Let P be the product of three chains. Determine all sequences μ1 ≥ μ2 ≥ ·· · ≥ μk that are the sizes of the chains in some partition of P into chains. See [6] for the analogous result for two chains, and [4] fo...

This is a paper about the beauty of the permutation method. New and shorter proofs are given for the theorem [P. L. Erdős and G. O. H. Katona, J. Combin. Theory. Ser. A, 43 (1986), pp. 58–69; S. Shahriari, Discrete Math., 162 (1996), pp. 229–238] determining all extremal two-part Sperner families and for the uniqueness of k-Sperner families of maximum size [P. Erdős, Bull. Amer. Math. Soc., 51 ...

Methods of local approximations based on truncated Taylor series are well understood; several methods to compute bounds for the approximation errors are available (Christensen and Christensen, 2006), (Powell, 1981), (Shahriari, 2006). The use of Taylor approximations is convenient, among others, because methods to determine the approximation accuracy are well established. Taylor approximations ...

ashura event is one of the most important historical events thathas gained a great deal of attention not only from muslim scholars but also from many non-muslims as well. considering historical-cultural relation betweeniranand arabs, especially iniraq, ashura has emerged as a common element in culture of both nations. this helps us to make comparative studies on the two cultures.  in addition, ...

A process is a unique combination of manpower, machines, methods and materials in providing a product or service. Process capability indices have been used in the manufacturing industry to provide quantitative measures of process potential and performance. High quality production provides advantages such as cost saving, reduced scrap or remanufacturing, higher yield and increased customer satis...
