We characterized in Theorem 3.4 of [1] the closure and interior operators of induced spaces introduced by Lowen. The author of [2] proposed an open problem: Can Theorem 3.4 in [1] be generalized to lattice value induc...

Since the stability domain of polynomial family is not a convex set in either coefficient space or parameter space, it is important to investigate the condition of stable polynomial set whose convex hull is also stabl...

According to our earlier suggestion of defect structure model of LiNbO3: Mg, the threshold concentration should be 5.3 mol% MgO in congruent crystals. Recently, we measured the polarized O-H stretching-vibr...
B. G Zhang introduced an oscillatory and asymptotic behaviour of the equation X′(t)+p(t)X(t-[t])=0, t≥0, (1) where [t] denotes the greatest integer function.Now, we consider in a broad sense the first order nonlinear

A PL homotopy method (KNA method in short) was presented in Ref.[1] for the problem of locating zeroes of any polynomial of form f(z)=zn+sum from k=1 to n ak zn-k. Due to the intro...
Boolean function is a powerful tool for the study of digital systems. The functions independent of some argument and the functions linear with some argument are ex tensively applied to fault diagnosis of digital syste...

Ⅰ. INTRODUCTION AND RESULT Let H be a Hilbert space with its inner product (· , ·) and norm ‖·‖. Let etA be a C0-semigroup on H with the infinitesimal generator A and
Suppose {Xn} be a sequence of stationary and φ-mixed random variables (for example, see Ref. [1]), the common unknown probability density of Xn′s is f(x). For each n≥1, the kernel estimators of f(x), based on...
There were many papers with deviating arguments on oscillation of the first order uonlinear differential equations in the last ten years. Y. Kitamura and T. Kusano recently obtained better results for the superlinear ...
The limiting behavior of Cs(?)rg(?)-R(?)v(?)sz’s increments of partial sums of i. i. d. random variables have been obtained with the help of partial sums of strong approximation by Wiener process from the increments ...
