The generalization for singular varieties is due to Brasselet–Schürmann–Yokura. Following the work of Weber, we investigate its equivariant version for (possibly singular) toric varieties. The local decomposition of the Hirzebruch class to the fixed points of the torus action and a formula for the local class in terms of the defining fan are recalled. After this review part, we prove the positivity of local Hirzebruch classes for all toric varieties, thus proving false the alleged counterexample given by Weber.","lang":"eng"}],"article_processing_charge":"No","page":"560-574","volume":53,"quality_controlled":"1","doi":"10.1112/blms.12442","isi":1,"scopus_import":"1","publication_identifier":{"eissn":["1469-2120"],"issn":["0024-6093"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","oa":1,"publisher":"Wiley","citation":{"apa":"Rychlewicz, K.
