A Paedagogic Example of Cut-Elimination
... where Π and Γ are lists of predicate formulas, ‘→’ is called the sequent arrow. For someone used to the Hilbert-style calculus, where one only works with single formulas, trying to deduce the end formula from a list of axioms by only two rules, namely modus ponens and generalization, this seems a ra ...

Part II Permutations, Cosets and Direct Product
... Similalry, g : H −→ aH defined by g(x) = ax is bijective. So, H, Ha, aH have same cardinality. Notationally, |H| = |Ha| = |aH| 3. If G is abelian then Ha = aH for all a ∈ G. Lemma 10.2. For the relation ∼R , the equivalence class of a ∈ G is the right coset Ha. For the relation ∼L , the equivalence ...
