Higgs Physics and the Equivalence TheoremAbstract: The equivalence theorem is an extremely useful tool to calculate heavy Higgs {\it and} topquark effects for processes that have centerofmassenergies (much) larger than the $W$ boson mass. After an explanation of the renormalization procedures involved, the results for one and twoloop radiative corrections to the fermionic Higgs decay, $H\rightarrow f\bar f$, are given and discussed. Finally, the renormalization scheme dependence is examined, and the reliability of the perturbative series is investigated.
