Isomorphisms of scattered automatic linear orders
We prove that the isomorphism of scattered tree automatic linear orders as well as the existence of automorphisms of scattered word automatic linear orders are undecidable. For the existence of automatic automorphisms of word automatic linear orders, we determine the exact level of undecidability in the arithmetical hierarchy.
متن کاملplayed on partial isomorphisms
We study the poset 〈Iκ ,⊆〉 as a measure of how similar the structures A and B are to each other. A subset X of Iκ has the κ back-and-forth property if for all λ < κ ∀p ∈ X[∀a ∈ λA∃b ∈ B (p ∪ {〈a(i), b(i)〉 : i < λ} ∈ X) ∧ ∀b ∈ λB∃a ∈ A(p ∪ {〈a(i), b(i)〉 : i < λ} ∈ X)]. It is obvious that there is a largest κ-back-and-forth set which we denote by I∗ κ . The structures A and B are said to be parti...
متن کاملOn orders induced by implications
In this paper, the orders induced by the residual implications obtained from uninorms are investigated. A necessary and sufficient condition is presented so that the ordinal sum of fuzzy implications satisfies the law of importation with a t-norm $T$. Some relationships between the orders induced by an ordinal sum implication and its summands are determined. The algebraic structures obtained fr...
متن کاملOn lattice isomorphisms of inverse semigroups, II
A lattice isomorphism between inverse semigroups S and T is an isomorphism between their lattices of inverse subsemigroups. When S is aperiodic, it has long been known that a bijection is induced between S and T . Various authors have introduced successively weaker ‘archimedean’ hypotheses under which this bijection is necessarily an isomorphism, naturally inducing the original lattice isomorph...
متن کاملOn Isomorphisms of Standard Operator Algebras
The aim of this paper is to show that between standard operator algebras every bijective map with a certain multiplicativity property related to the Jordan triple isomorphisms of associative rings is automatically additive.
