  • Exact formula for the sum of the squares of spherical Bessel and Neumann function of the same order 
    Jayasinghe, W.J.M.L.P.; Piyadasa, R.A.D. (University of Kelaniya, 2008)
    The sum of the squares of the spherical Bessel and Neumann function of the same order (SSSBN)is the square of the modulus of the Hankel function when the argument of all function are real, and is very important in ...
  • Singularities of the elastic S-matrix element 
    Jayasinghe, W.J.M.L.P.; Piyadasa, R.A.D. (University of Kelaniya, 2008)
    It is well known that the standard conventional method of integral equations is not able to explain the analyticity of the elastic S-matrix element for the nuclear optical potential including the Coulomb potential. It ...
  • Structure of primitive Pythagorean triples and the proof of a Fermat's theorem 
    Jayasinghe, W.J.M.L.P.; Piyadasa, R.A.D. (University of Kelaniya, 2008)
    In a short survey of survey of primitive Pythagorean triples (x,y,z) 0 < x < y < z , we have found that one of x, y, z is divisible by 5 and z is not divisible by 3, there are Pythagorean triples whose corresponding ...
