skos:broadMatch is generally used to relate a concept in one knowledge scheme to a more general concept in another scheme while skos:broader is used to create hierarchical links between concepts within the same knowledge scheme. It may be the case that skos:broader more accurately expresses the intended relationship between a literary tradition and the conceptual works which comprise it.
skos:broadMatch is one of the ‘mapping’ properties that “are used to state mapping (alignment) links between SKOS concepts in different concept schemes, where the links are inherent in the meaning of the linked concepts.” (https://www.w3.org/TR/2009/REC-skos-reference-20090818/#mapping). skos:broader is used for hierarchical relations between concepts within the same scheme, “The properties skos:broader and skos:narrower are used to assert a direct hierarchical link between two SKOS concepts.” (https://www.w3.org/TR/2009/REC-skos-reference-20090818/#semantic-relations).
