Fixed point theorems for generalized weakly contractive mappings

In this paper several fixed point theorems for generalized weakly contractive mappings in a metric space setting are proved. The set of generalized weakly contractive mappings considered in this paper contains the family...

On the Liu and almost unbiased Liu estimators in the presence of multicollinearity with heteroscedastic or correlated errors

This paper introduces a new biased estimator, namely, almost unbiased Liu estimator (AULE) of β for the multiple linear regression model with heteroscedastics and/or correlated errors and suffers from the problem of mult...

On a certain subclass of meromorphic univalent functions with fixed second positive coefficients

In the present paper, we consider the subclass of meromorphic univalent functions S<SUB>p</SUB><SUP>*</SUP>[k,α,β,c] with fixed second positive coefficient. The object of the present paper is to s...

Families of quasi-pseudo-metrics generated by probabilistic quasi-pseudo-metric spaces

This paper contains a study of families of quasi-pseudo-metrics (the concept of a quasi-pseudo-metric was introduced by Wilson (1931) , Albert (1941) and Kelly (1963)) generated by probabilistic quasi-pseudo-metric-space...
