RT journal article T1 Flow invariants in the classification of Leavitt path algebras A1 Abrams, G. A1 Louly, A. A1 Pardo Espino, Enrique A1 Smith, C. A2 Matemáticas K1 Leavitt path algebra K1 Morita equivalence K1 Flow equivalence AB We analyze in the context of Leavitt path algebras some graph operations introduced in the context of symbolic dynamics by Williams, Parry and Sullivan, and Franks. We show that these operations induce Morita equivalence of the corresponding Leavitt path algebras. As a consequence we obtain our two main results: the first gives sufficient conditions for which the Leavitt path algebras in a certain class are Morita equivalent, while the second gives sufficient conditions which yield isomorphisms. We discuss a possible approach to establishing whether or not these conditions are also in fact necessary. In the final section we present many additional operations on graphs which preserve Morita equivalence (resp. isomorphism) of the corresponding Leavitt path algebras SN 0021-8693 YR 2011 FD 2011-01-01T00:00:00Z LK http://hdl.handle.net/10498/16098 UL http://hdl.handle.net/10498/16098 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 10-may-2026
