To this end recall from Definition 1.15 in [4] that T is well generated if there is a regular cardinal α such that condition (2) in the following theorem holds.

The reason all coherent 2-groups with the same underlying weak 2-group are isomorphic is that we have defined a homomorphism of coherent 2-groups to be a weak monoidal functor,

A pointed regular category is subtractive if and only if every span in it is subtractive, and moreover, the functor S not only preserves but also reflects subtractive spans..

Without loss of generality we assume that the upper and lower path of the polyomino start in (0 , 0). Figure 1 depicts a parallelogram polyomino having area 14 and semi-perimeter

This article deals with Chogoshvili cohomotopy functors which are defined by extending a cohomology functor given on some special auxiliary subcategories of the category of

By requiring explicit de®nition of schema, self-concept, relationship scripts and enactment, and the examination of congruence between the elements the framework is a useful device

4. Consistent with most MRP implementations, we assume that the # ow of work in a multistage production environment can be modeled as the sum of four independent components:

A model has been developed which shows how a small firm’s advantages in respect of service quality (as identified at stage 1 of the research) interact with these principal
