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 ...

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 ...

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 ...

ABSTRACT
metric d<2�� (1- 2; }'dt' (I-�� t'-r' (d02+sin2 Od��' )
appears to behave badly near r = 2m, where gtt becomes zero, and grr tends to
infinity1• There is a pathology in the line element that ...
The structure of Fermat's triples can be immensely useful in finding a simple proof of
Fermata's Last Theorem. In this contribution, the structure of Fermat's triples 1s
determined using Fermat's little theorem producing ...
