Solutions, in terms of special functions, of all wave equations uxx − utt = V (x)u(t, x), characterised by eight inequivalent time independent potentials and by variables separation, have been found. The real valueness and the properties of the solutions produced by computer algebra programs are not always manifest and in this work we provide ready to use solutions. We discuss especially the po...

The lowest representatives of the Form Factors relative to the trace operators of N = 1 Super Sinh-Gordon Model are exactly calculated. The novelty of their determination consists in solving a coupled set of unitarity and crossing equations. Analytic continuations of the Form Factors as functions of the coupling constant allows the study of interesting models in a uniform way, among these the l...

Trong nhà trường phổ thông, giáo dục đạo đức là một trong những nhiệm vụ được xác định có vai trò quan trọng, bởi đây yếu tố nền tảng. Để đạt mục tiêu cho học sinh, các thông thể tiến hành qua nhiều cách thức khác nhau như: hoạt động dạy học, sinh tập thể, xã hội, trải nghiệm, ngoài ra nó còn quá trình tự tu dưỡng, rèn luyện của mỗi cá nhân sinh,… đó, thực hiện việc nghiệm con đường ưu thế, man...

With the aid of symbolic computation, the sinh-Gordon equation expansion method is extended to seek Jacobi elliptic function solutions of (2+1)-dimensional long wave-short wave resonance interaction equation, which describe the long and short waves propagation at an angle to each other in a two-layer fluid. As a result, new Jacobi elliptic function solutions are obtained. When the modulus m of ...

In this paper, the skew-elliptical sinh-alpha-power distribution is developed as a natural follow-up to log-linear Birnbaum–Saunders alpha-power distribution, previously studied in literature. Special cases include ordinary and skewed distributions. As shown, it able surpass sinh-normal models when fitting data sets with high (above expected sinh-normal) degrees of asymmetry. Maximum likelihood...
