Some new oscillation theorems are established for the second order nonlinear differential equations with damping of the form where p(t) and q(t) are allowed to chan
In this paper, the Cauchy type integral for M-analytic function is investigated which is by definition the regular solution of the elliptic system f_x+Mf_y=0, w
Let X be a d-dimensional random vector with unknown density function f(z)=f(z<sub>1</sub>, ···, z<sub>d</sub>), and let f<sub>n</sub> be teh nearest
