External routines: In order to make further simplifications on the expressions obtained the library calls the Symbolic Manipulation System FORM program [1].
Nature of problem: The decomposition of an Yukawa interaction invariant under SO(class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0010465516000308&_mathId=si40.gif&_user=111111111&_pii=S0010465516000308&_rdoc=1&_issn=00104655&md5=81691840a2d0eb049fcbd766ad54362e" title="Click to view the MathML source">2Nclass="mathContainer hidden">class="mathCode">) in terms of SU (class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0010465516000308&_mathId=si41.gif&_user=111111111&_pii=S0010465516000308&_rdoc=1&_issn=00104655&md5=c77a0d228ee90ae29a2c26dedf15015a" title="Click to view the MathML source">Nclass="mathContainer hidden">class="mathCode">) fields.
Solution method: We make use of the oscillator expansion formalism, where the SO(class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0010465516000308&_mathId=si40.gif&_user=111111111&_pii=S0010465516000308&_rdoc=1&_issn=00104655&md5=81691840a2d0eb049fcbd766ad54362e" title="Click to view the MathML source">2Nclass="mathContainer hidden">class="mathCode">) spinor representations are expressed in terms of creation and annihilation operators of a Grassmann algebra acting on a vacuum state.
Running time: It depends on the input expressions, it can take a few seconds or more for very large representations (because of memory exhaustion).
