We then use this characterization to prove a result that relates these isotropic subspaces with linear systems supported on the arrangement, for arrangements with isolated non-normal crossings of a particular form. 000131387 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000131387 590__ $$a0.667$$b2011 000131387 591__ $$aMATHEMATICS$$b110 / 289 = 0.381$$c2011$$dQ2$$eT2 000131387 591__ $$aMATHEMATICS, APPLIED$$b135 / 245 = 0.551$$c2011$$dQ3$$eT2 000131387 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000131387 773__ $$g24, 2 (2011), 527-538$$pRev. mat. complut.$$tRevista Matematica Complutense$$x1139-1138 000131387 8564_ $$s186422$$uhttps://zaguan.unizar.es/record/131387/files/texto_completo.pdf$$yPostprint 000131387 8564_ $$s1722240$$uhttps://zaguan.unizar.es/record/131387/files/texto_completo.jpg?subformat=icon$$xicon$$yPostprint 000131387 909CO $$ooai:zaguan.unizar.es:131387$$particulos$$pdriver 000131387 951__ $$a2024-02-08-14:37:51 000131387 980__ $$aARTICLE
