We also obtain an explicit representation of local solutions to the associated wave equation by using the classical d'Alembert's formula.doi:10.1007/S00013-010-0209-YEdgardo Alvarez-PardoMahamadi WarmaArchiv der MathematikM. Warma and E. Alvarez-Pardo. The one-dimensional wave equation with ...
摘要: In order to compensate the lack of Poincare's inequality in (mathbb {R}^{n}) and for wider class of relaxation functions, we are going to use weighted spaces to establish a very general decay rate of solutions of viscoelastic wave equations in Kirchhoff-type.关键词:...
1.By the methods of reducing order and Euler s eigenvalues,we obtain the general solution formula to one kind of systems of three dimensional second order ordinary differential equation with constant coefficients.采用降阶和特征根 (欧拉 )方法 ,给出了一类三维二阶常系数微分方程组的通解公式 ,并通过...
a.Also calledspecial relativity.the first part of Einstein's two-part theory, based on the axioms that physical laws have the same form throughout the universe and that the velocity of light in a vacuum is a universal constant, from which is derived the mass-energy equation,E = mc2. ...
An analog of the Weyl character formula has been conjectured by Lusztig and proved generically, but not yet for all primes p. For applications to topology and number theory, there have been efforts to study integral representations of a finite group G, i.e., homomorphisms of G into GL(n...

To facilitate comparison with a similar population in the Reference Values Project10,“direct” travel distance × 0.8 was calculated according to the formula TDdirect = (0.45 × TD subtracted + 0.21 × height + 0.08) × 0.810, and used for the main ...
A correctional function that considers the effects of the rarefaction wave from the hollow core of explosive charge is adopted to correct the Gurney formula. Our purpose is to develop a new formula to predict the initial fragment velocity of novel warheads with hollow core. Fig. 1 shows that ...
