... A mapping is called bijective if it is injective and onto. Let f : A → B, g : B → C be mappings. The symbol g ◦ f stands for their composition, i.e. a mapping from A to C defined by (g ◦ f )(x) = g(f (x)), x ∈ A. Let f : A → B be injective and onto. Inversion mapping f −1 : B → A is defined by f −1 ...

... These shortcut rules will be utilised when FOPL formulas are transformed into a form that is easy to process and understand. This form will be used when FOPL formulas are compared with conceptual graphs. In this paper, we do not present proof theory for FOPL. Instead, we state the following short re ...

AMTH142 Lecture 7 Maxima — Numbers, Variables and Expressions
... You might think that c should now have the value 16. This is done by some other computer algebra systems but it leads to serious problems. The rule used by Maxima is clear and consistent: Once a variable has been assigned a value this value is not changed by subsequent assignments, except, of course ...

Not much is known on admissible rules in intuitionistic predicate logic Q-INT 1 , even less in extensions of Q-INT. In his pioneering work S.Ghilardi introduced uni cation in prop ...
