Left, right, and inner socles of associative systems

We investigate the basic properties of the different socles that can be considered in not necessarily semiprime associative systems. Among other things, we show that the socle defined as the sum of minimal (or minimal and trivial) inner ideals is always an ideal. When trivial inner ideals are included, this inner socle contains the socles defined in terms of minimal left or right ideals.

Hawking Absorption and Planck Absolute Entropy of Kerr-Newman Black Hole

We find the existence of a quantum thermal effect, “Hawking absorption.” near the inner horizon of the Kerr–Newman black hole. Redefining the entropy, temperature, angular velocity, and electric potential of the black hole, we give a new formulation of the Bekenstein–Smarr formula. The redefined entropy vanishes for absolute zero temperature of the black hole and hence it is interpreted as the Planck absolute entropy of the KN black hole.     

Asymptotic Behavior of Sobolev-Type Orthogonal Polynomials on a Rectifiable Jordan Curve or Arc

Our object of study is the asymptotic behavior of the sequence of polynomials orthogonal with respect to the discrete Sobolev inner product <formula> \langle f, g \rangle = ∈t_{E} f(ξ) \overline{g(ξ)} ρ(ξ) |d ξ|+ f(Z) A g(Z)^H, </formula> where E is a rectifiable Jordan curve or arc in the complex plane f(Z) = (f(z_1), \ldots, f^{(l_1)}(z_1) , \ldots , f(z_m) , \ldots ,f^{(l_m)}(z_m)), A is an M \times M Hermitian matrix, M l ₁ + ⋅s + l _m + m , |d ξ| denotes the arc length measure, ρ is a nonnegative function on E , and z _i ∈Ω, i=1,2,\ldots,m , where Ω is the exterior region to E .

会计信息化问题的探讨

论述了随着经济的发展，会计信息化在冲击传统会计和会计电算化的同时。也面临着经济环境等因素的制约和影响，只有加强内部控制制度的建设，加强人才的培养，加强财务软件的开发，才能加快会计信息化发展的步伐。     

内蒙古土默特旗科达穗及种子化石研究

对发现于内蒙古土默特旗上石炭统一下二叠统的几种科达穗化石及种子类化石进行了研究,经鉴定确认其中有2个为新种,分别定名为长爪科达穗Cordaitanthuslongibracteatussp.nov.和多泡石籽Car polithusmultibullatussp.nov..这些珍贵的繁殖器官的发现,表明晚石炭世一早二叠世种子演化已达相当水平,对于研究科达类的演化过程具有重要的研究价值.

The Reasons Why Rochester Could Fall in Love with Jane.Eyre

love is an eternal theme of human being.Concerning with the literature productions that sing praise of love,it is necessary to talk about Jane.Eyre.It differs from others.Jane.Eyre portrays a story that an upper class gentleman falls in love with a small,plain,poor governess.We can't help asking why.Why could Rochester fall in love with Jane? This paper will quote the statement of Rochester himself and analyze the reasons.The purpose of the paper is to emphasize the essence of love---it is not outer beauty,but inner beauty,so that it could evoke people's respect for inner beauty.
