=====Generalized MV-algebras===== Abbreviation: **GMV** ====Definition==== A \emph{generalized MV-algebra} is a [[residuated lattices]] $\mathbf{L}=\langle L,\vee, \wedge, \cdot, e, \backslash, /\rangle$ such that $x\vee y=x/(y\backslash x\wedge e)$, $x\vee y=(x/y\wedge e)\backslash y$ ==Morphisms== Let $\mathbf{L}$ and $\mathbf{M}$ be generalized MV-algebras. A morphism from $\mathbf{L}$ to $\mathbf{M}$ is a function $h:L\rightarrow M$ that is a homomorphism: $h(x\vee y)=h(x)\vee h(y)$, $h(x\wedge y)=h(x)\wedge h(y)$, $h(x\cdot y)=h(x)\cdot h(y)$, $h(x\backslash y)=h(x)\backslash h(y)$, $h(x/y)=h(x)/h(y)$, $h(e)=e$ ====Examples==== Example 1: ====Basic results==== ====Properties==== ^[[Classtype]] |variety | ^[[Equational theory]] |decidable [http://www.chapman.edu/~jipsen/lgroups/GMVDecisionProc.html implementation] | ^[[Quasiequational theory]] | | ^[[First-order theory]] | | ^[[Locally finite]] |no | ^[[Residual size]] |unbounded | ^[[Congruence distributive]] |yes | ^[[Congruence modular]] |yes | ^[[Congruence n-permutable]] |yes, $n=2$ | ^[[Congruence regular]] |no | ^[[Congruence e-regular]] |yes | ^[[Congruence uniform]] |no | ^[[Congruence extension property]] | | ^[[Definable principal congruences]] | | ^[[Equationally def. pr. cong.]] | | ^[[Amalgamation property]] | | ^[[Strong amalgamation property]] | | ^[[Epimorphisms are surjective]] | | ====Finite members==== $\begin{array}{lr} f(1)= &1\\ f(2)= &1\\ f(3)= &\\ f(4)= &\\ f(5)= &\\ f(6)= &\\ \end{array}$ ====Subclasses==== [[Commutative generalized MV-algebras]] [[Integral generalized MV-algebras]] [[MV-algebras]] ====Superclasses==== [[Generalized BL-algebras]] ====References==== [(Ln19xx> )]
