Let Ap(n)(p, n ∈ N = {1,2,…}) denote the class of functions of the form f(z) = z^p + ap+nZ^p+n +…which are analytic in the unit disc E = {z: | z |< 1}. By
In this paper,a class of new biased estimators for linear model is proposed by modifying the singular values of the design matrix so as to directly overcome the
This paper is devoted to the study of the logical properties of BCK algebras. For formalized BCK algebra theory T, it is proved that T is preserved under submod
