In this paper we estimate xtn S3 (p, m) , the n-extent of various lens spaces. We give numerical evidence for extending certain results of D. G. Yang [Duke Math. J., 74 (1994), 531-545.] to primes p between 11 and 37. We explain the implication of our results for the topology of 4-dimensional manifolds of positive sectional curvature with nontrivial isometric p-actions.

We consider a class of partitioning problems where the partitioned set is a finite set of real numbers and the objective function of a partition is a function of the vector whose coordinates are the sums of the elements in each part of the given partition (the number of such parts is assumed given). We obtain an explicit solution of such partitioning problem with polynomial complexity bounds. c...

The different association behaviours of surfactants in water and other solvents have stimulated the interest to elucidate how the solvent properties influence aggregation, and many studies have been performed to gain information on the role of the solvent in the aggregation phenomenon of amphiphiles. These investigations have focused mainly on two essential aspects: namely the nature of the int...
