 +   <hidden TTP97-12  Higgs Decay to Top Quarks at O(\alpha_s^2)  > Three-loop corrections to the scalar and pseudo-scalar 
 + current correlator are calculated.  By applying the large momentum 
 + expansion mass terms up to order (m^2/q^2)^4 are evaluated 
 + analytically. As an application O(\alpha_s^2) corrections to 
 + the decay of a scalar and pseudo-scalar Higgs boson into top quarks 
 + are considered. It is shown that for a Higgs mass not far above the 
 + $t\bar{t}$ threshold these higher order mass corrections are necessary 
 + to get reliable results.
