On the complexity of the Whitehead minimization problem

The Whitehead minimization problem consists in finding a minimum size element in the automorphic orbit of a word, a cyclic word or a finitely generated subgroup in a finite rank free group. We give the first fully polynomial algorithm to solve this problem, that is, an algorithm that is polynomial both in the length of the input word and in the rank of the free group. Earlier algorithms had an exponential dependency in the rank of the free group. It follows that the primitivity problem – to decide whether a word is an element of some basis of the free group – and the free factor problem can also be solved in polynomial time.

Maria-Antònia Oliver, traductora

Maria-Antònia Oliver i Cabrer (Manacor, 1946) és una de les poques traductores al català que han aprofundit en la teoria de la traducció i que han plasmat els seus pensaments sobre paper. Coneixem a bastament el seu vessant literari gràcies a un bon grapat d’estudis que s’han dut a terme des de diverses universitats dels Països Catalans i també des d’algunes de fora de les nostres fronteres. Amb tot, la faceta de torsimany sovint ha estat esmentada de passada, malgrat hagi portat al català autors i autores de renom com ara Virginia Woolf, Herman Melville, Italo Calvino o Mark Twain. Maria-Antònia Oliver, traductora situa l’autora en el moment en què ha traduït, se centra en la seva idea sobre la traducció, cataloga les seves traduccions i visibilitza la figura d’una traductora prolífica.
