QGP热力学势中的屏蔽和阻尼效应

采用含有Debye屏蔽和阻尼效应的胶子谱函数, 在实时温度QCD理论的框架下计算了夸克胶子等离子体中有效二圈热力学势, 得到了依赖于胶子屏蔽和阻尼作为物理参数的解析结果. 数值计算表明, 我们的结果与格点QCD理论计算的最新结果在温度T≥2T_c时相符.     

INTERSECTION OF PRIME SUBMODULES AND DIMENSION OF MODULES

The aim of this paper is to study the conditions by which a P-prime submodule can be expressed as a finite intersection or union of P-prime submodules. Also corresponding to dimension and rank of modules, some equivalent conditions for a ring to be a Dedekind domain are given.

CAP-子群与p-幂零性

设G是有限群。H是G的一个正规子群。P是|H|的一个素因子。P是H的一个Sylow p-子群。若下列条件之一满足。则H是p-幂零：1)P的极大子群都是G的CAP-子群且(|H|，P-1)=1；2)P的二次极大子群都是G的CAP-子群且(|H|，P^2-1)=1。特别地，若进一步假设G／H为P-幂零且(|G|，P-1)=1或(|G|，P^2-1)=1。则G自身亦为P-幂零。     

重视直观性教学法在高等数学教学中的应用

在多年的教学实践及理论研究基础上提出了在高等数学教学中应大力提倡和广泛应用的方法——直观性教学法 ,即在教学过程中运用各种手段在概念、定理、证明、解题中突出其直观性 ,培养学生的数学直觉 ,提高其数学文化素质 .直观性教学法可以培养学生学习兴趣 ,提高记忆品质 ,提高学习效率 .本文先从数学的本质及人类思想的规律两方面理论上论证了直观性教学法的可行性 ,又从高等数学的教材及教学两方面实际论证了直观性教学法的必要性 .最后以三个教学案例具体说明了直观性教学法的实施方法

Surface Gravity on the Horizon of η- ξ Spacetime

We investigate the two methods of defining the surface gravity ,κ on the horizon, which are the metric definition and the definition given by the spacetime conformal method. It is found that the latter is of greater generality. By this method, we find that ,κ of η- ξ spacetime is equal to the exponent factor α in the coordinate transformation, which confirms the argument that η- ξ spacetime can be considered as the background spacetime for finitetemperature field theories. The reasons why the metric definition of ,κ can not be applied in η- ξ spacetime are presented.     

Soliton Solution of SU（3） Gauge Fields at Finite Temperature

Starting from a soliton model of SU（3） gauge fields, we investigate the behaviour of the model at finite temperature. it is found that colour confinement at zero temperature can be melted away under high temperatures.     

CHARACTERIZATIONS OF JORDAN (?)-SKEW MULTIPLICATIVE MAPS ON OPERATOR ALGEBRAS OF INDEFINITE INNER PRODUCT SPACES

Let H and K be indefinite inner product spaces. This paper shows that a bijective map φ:B(H)→B(K) satisfies φ(AB B A) =φ(A)φ(5) φ(B) φ(A) for every pair A,B ∈B(H) if and only if either φ(A) = cU AU for all A or φ(A) = cUA U for all A; φsatisfies φ(AB A) = φ(A)φ(B) φ(A) for every pair A,B ∈B(H) if and only if either φ(A) = UAV for all A or φ(A) = UA V for all A, where A denotes the indefinite conjugate of A, U and V are bounded invertible linear or conjugate linear operators with U U = c-1I and V V = cI for some nonzero real number c.
