## Abstract We generalize spherical harmonics expansions of scalar functions to expansions of alternating differential forms (β__q__βformsβ). To this end we develop a calculus for the use of spherical coβordinates for __q__βforms and determine the eigenβ__q__βforms of the Beltramiβoperator on __S__
