On Some L_r-Biharmonic Euclidean Hypersurfaces
Journal Title: Journal of Mathematics and Applications - Year 2016, Vol 39, Issue
Abstract
In decade eighty, Bang-Yen Chen introduced the concept of biharmonic hypersurface in the Euclidean space. An isometrically immersed hypersurface x : M^n → E^{n+1} is said to be biharmonic if ∆^2x = 0, where ∆ is the Laplace operator. We study the L_r-biharmonic hypersurfaces as a generalization of biharmonic ones, where L_r is the linearized operator of the (r + 1)th mean curvature of the hypersurface and in special case we have L_0 = ∆. We prove that L_r-biharmonic hypersurface of L_r-finite type and also L_r-biharmonic hypersurface with at most two distinct principal curvatures in Euclidean spaces are r-minimal.

On the Derivative of a Polynomial with Prescribed Zeros
For a polynomial [formula] of degree n having all its zeros in |z| ≤ K, K ≥ 1it is known that [formula]. By assuming a possible zero of order m, 0 ≤m ≤ n – 4, at z=0, of p(z) for n ≥ k + m + 1 with integer k ≥ 3 we have...
Approximate controllability of the impulsive semilinear heat equation
In this paper we apply Rothe’s Fixed Point Theorem to prove the interior approximate controllability of the following semilinear impulsive Heat Equation [formula], where k = 1,2,...,p, Ω is a bounded domain in R^N (N ≥ 1...
Approximation by Szász Type Operators Including Sheffer Polynomials
In present article, we discuss voronowskaya type theorem, weighted approximation in terms of weighted modulus of continuity for Szász type operators using Sheffer polynomials. Lastly, we investigate statistical approxima...
About a Class of Analytic Functions Defined by Noor-Sǎlǎgean Integral Operator
In this paper we introduce a new integral operator as the convolution of the Noor and Sălăgean integral operators. With this integral operator we define the class C_{NS}(α), where α∈[0,1) and we study some properties of...
Fekete-Szegő Problems for Certain Class of Analytic Functions Associated with Quasi-Subordination
In this paper, we determine the coeffcient estimates and the Fekete-Szegő inequalities for M_q^α (γ,λ,φ), the class of analytic and univalent functions associated with quasi-subordination.
