Rearrangements and category

On the category of geometric spaces and the category of (geometric) hypergroups

‎In this paper first we define the morphism between geometric spaces in two different types‎. ‎We construct two categories of $uu$ and $l$ from geometric spaces then investigate some properties of the two categories‎, ‎for instance $uu$ is topological‎. ‎The relation between hypergroups and geometric spaces is studied‎. ‎By constructing the category $qh$ of $H_{v}$-groups we answer the question...

Rearrangements of the blood group RhD gene associated with the DVI category phenotype.

The Rh (Rhesus) blood group antigens, D, Cc, and Ee, are carried by three unglycosylated membrane proteins of the human erythrocytes encoded by two highly related genes, D and CcEe. The major antigen, D, is a mosaic composed of at least nine determinants (epD1 through epD9). The lack of expression of some of these D epitopes at the surface of variant red blood cells defines the so-called D cate...

Category use and category learning.

Categorization models based on laboratory research focus on a narrower range of explanatory constructs than appears necessary for explaining the structure of natural categories. This mismatch is caused by the reliance on classification as the basis of laboratory studies. Category representations are formed in the process of interacting with category members. Thus, laboratory studies must explor...

CATEGORY OF (POM)L-FUZZY GRAPHS AND HYPERGRAPHS

In this note by considering a complete lattice L, we define thenotion of an L-Fuzzy hyperrelation on a given non-empty set X. Then wedefine the concepts of (POM)L-Fuzzy graph, hypergraph and subhypergroupand obtain some related results. In particular we construct the categories ofthe above mentioned notions, and give a (full and faithful) functor form thecategory of (POM)L-Fuzzy subhypergroups ...
