 Invariance of domain theorems for condensing multivalued vector fields Bull. Korean Math. Soc. 2010 Vol. 47, No. 1, 121-129 https://doi.org/10.4134/BKMS.2010.47.1.121Printed January 1, 2010 In-Sook Kim Sungkyunkwan University Abstract : Using a degree theory for countably condensing multivalued maps, we show that under certain conditions an invariance of domain theorem holds for countably condensing or countably $k$-contractive multivalued vector fields. Keywords : invariance of domain, countably condensing, multivalued vector fields, degree theory MSC numbers : 47H09, 54C60, 47H11 Downloads: Full-text PDF
