Studia Logica, 73(2), 183-195.http://hdl.handle.net/10400.13/3457This paper focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. We propose for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction, proposed by Hansson [Han94] to construct classical AGM contractions and belief base contractions. This construction works out the unsolved problem pointed out by Hansson in [Han99, pp. 369].engLogic of theory changeBelief basesKernel contractionMultiple contraction.Faculdade de Ciências Exatas e da Engenhariajournal article10.1023/A:1022927828817
