Generalized Cardinal Properties of Lattices and Lattice Ordered Groups
Ján Jakubík · Czechoslovak Mathematical Journal · 2004
We denote by K the class of all cardinals; put K′ = K ⋃ {α}. Let be a class of algebraic systems. A generalized cardinal property f on is defined to be a rule which assings to each A ∈ an element fA of K′ such that, whenever A1, A2 ∈ and A1 ≃ A2, then fA 1 = fA 2. In this paper we are interested mainly in the cases when (i) is the class of all bounded lattices B having more than one element, or (ii) is a class of lattice ordered groups.
