A Mond–Weir type dual for a class of nondifferentiable minimax fractional programming problem is considered. Appropriate duality results are proved involving (F,a,q,d)-pseudoconvex functions. 2005 Elsevier Inc. All rights reserved.

OBSERVE the title of the building we are assembled to dedicate-the Mitchell Memorial Building of the Philadelphia Orthopaedic Hospital and Infirmary for Nervous Diseases. It is not the S. Weir Mitchell or the Weir Mitchell Memorial, but simply the "Mitchell Memorial" Building.2 As there are many Franklins but only one Franklin, so there are many Mitchells but only one Mitchell. I first saw Weir...

The present paper attempts to investigate the prediction of air entrainment rate and aeration efficiency of a free overfall jets issuing from a triangular sharp crested weir by using regression based modelling. The empirical equations, Support vector machine (polynomial and radial basis function) models and the linear regression techniques were applied on the triangular sharp crested weirs rela...

1. INTRODUCTION In a previous study, Weir & Schluter [1] (hereafter WS2007) argue that smaller average genetic distances between species in cooler latitudes represent faster rates of speciation relative to tropical species. Such an interpretation assumes clades evolve at constant rates across latitudes so that a hypothetical molecular clock ticks at the same rate, regardless of climate. By cont...

In this paper, the concept of ∂-quasiconvexity is introduced by using convexifactors. Mond-Weir-type and Schaible-type duals are associated with a multiobjective fractional programming problem, and various duality results are established under the assumptions of ∂-pseudoconvexity and ∂-quasiconvexity.
