A crucial step towards the axiomatization of this degree is provided by the generalized algebraic multiplicity of Esquinas and López-Gómez [8, 9, 25], X, and the axiomatization theorem of Mora-Corral [28, 32]. The latest result facilitates the axiomatization of the parity of Fitzpatrick and Pejsachowicz [12], o(· , [a, b]) , which provides the key step for establishing the uniqueness of the degree for Fredholm maps.}, organization = {Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.}, publisher = {Springer}, publisher = {Journal of Fixed Point Theory and Applications, 2022, 24(1), 8}, title = {Axiomatization of the degree of Fitzpatrick, Pejsachowicz and Rabier}, author = {López-Gómez, Julián and Sampedro Pascual, Juan Carlos}, }
