CONVERGENCE PROPERTIES OF MULTI-DIMENSIONAL NEAREST NEIGHBOR DENSITY ESTIMATES FOR THE CASE OF GENERAL KERNEL

In this paper we give weaker conditions to ensure the strong uniform consis-tency of multi-dimensional nearest neighbor (N.N.) estimates with non-uniform kernel andobtain the convergence rates of these estimates on an arbitrary bounded set. The ratescan not be improved in some sense. Obviously, the problem of strong convergence rates ata given point is its special case. The range of applications of estimates is extended.     

Probability Criterion in Inventory System with Bounded Emergency Order

In this paper,we consider the inventory system with a bounded emergency order,using aprobablility criterion.It is shown that there exist two critical numbers critical number x and x such that the optimalemergency order policy is order-up-to-x with a bound and the optimal regular order policy is order-up-to-x.     

ON A LINEAR EQUATIONS METHOD OF NONLINEAR POLYNOMIAL EQUATIONS-SOLVING

A method for solving nonlinear polynomial equations is given which avoids theappearance of redundant factors as in the previous characteristic set method developed bythe present author. The new method seems thus to be of much higher efficiency than theprevious one. It has the further advantage that numerical data may be inserted at willeither at the outset or during the procedure so far removal of factors by divisions may beavoided.     

NECESSARY AND SUFFICIENT CONDITIONS FOR G-STRUCTURES WITH LOGICAL RELATIONS TO FORM BOUNDED LATTICES IN RECONSTRUCTABILITY ANALYSIS

After a brief review of the basic notions the paper defines the G~L-structuresand their partial ordering. On this basis, the paper proves the necessary and sufficientconditions for G~L-structures to form bounded lattices.
