Also, a formula for the dimension of the space of quasihomogeneous polynomials of a given degree is derived. This admits an interpretation as a numerical adjunction formula for singular curves on the weighted projective plane2016http://zaguan.unizar.es/record/13181010.1215/21562261-3600184http://zaguan.unizar.es/record/131810oai:zaguan.unizar.es:131810info:eu-repo/grantAgreement/ES/DGA/E15info:eu-repo/grantAgreement/ES/MICINN/MTM2013-45710-C2-1-PKYOTO JOURNAL OF MATHEMATICS 56, 3 (2016), 575-598All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
