  • In fact, the notion of morphism in the category of logic systems being employed is the key to create or to block interactions.

    Combining Logics

  • From the categorial point of view, the process is the same as for algebraic fibring, the only difference being that the notion of morphism is stronger.

  • Hence a preordered set is a category in which there is at most one morphism between any two objects.

    Category Theory

  • On the other hand, suppose a category of logic systems in which the preservation of rules such as (*) or (**) above is required by the very notion of morphism.

    Combining Logics

  • Ellipses in phase space — curves of constant energy — then become isomorphism classes, because the oscillator motion is periodic, and for any A and B connected by a morphism, you can find another time evolution which takes B back into A.

  • We have stated above that, in a spatial setting, an impression of symmetry arises if a design is not changed by a group of automorphisms of the space, and we add to this that, as far as design is concerned, the underlying space is a setting for it, and any auto - morphism of the space is a certain change of this setting.
