An elegant and fast method for the calculation of geometrical structure coefficients needed for an expansion of a few-body wavefunction and interaction in hyperspherical harmonics has been proposed. A sum rule for the GSC has also been derived, which is useful for an independent check of the coefficients. The proposed method of computation is many orders of magnitude faster than conventional methods.

The integro-differential equation in two variables for a many boson system has been solved by expanding its solution in the complete set of Jacobi polynomials and subsequent projection. This results in a system of coupled differential equations. This has been solved for the triton. The integrals in the potential matrix elements can be done analyticaly for potentials having Gaussian type terms. Calculated binding energy for several simple potentials agree closely with those calculated by other methods.
