00925njm 22002777a 4500 dc López Gómez, Julián author Sampedro Pascual, Juan Carlos author 2020 This paper tries to establish a link between topological and algebraic methods in nonlinear analysis showing how the topological degree for Fredholm operators of index zero of Fitzpatrick, Pejsachowicz and Rabier [11] can be determined from the generalized algebraic multiplicity of Esquinas and López-Gómez [8], [7], [22], in the same vein as the Leray–Schauder degree can be calculated from the Schauder formula through the classical algebraic multiplicity. 0362-546X 10.1016/j.na.2020.112019 https://hdl.handle.net/20.500.14352/7596 https://doi.org/10.1016/j.na.2020.112019 https://www.sciencedirect.com/science/article/abs/pii/S0362546X20302315#!
