The class of primitive rings is obtained from this elementary class by omitting the sorts and language associated with the ideals, and is hence a pseudoelementary class. In this example it is an open question whether this pseudoelementary class is elementary. The class of exponentially closed fields is a pseudoelementary class that is not ...
A pseudo-class classifies document elements, such as : link or : visited, whereas a pseudo-element makes a selection that may consist of partial elements, such as :: first-line or :: first-letter. [7] Note the distinction between the double-colon notation used for pseudo-elements and the single-colon notation used for pseudo-classes.
The :hover pseudo-class in CSS allows developers to define the styles that should be applied to an element. The styles are applied when the user hovers their mouse pointer over the element. Unlike static CSS properties, the :hover pseudo-class targets an element only when a specific condition (hovering) is met. The styles are not applied at all ...
A relative pseudocomplement of a with respect to b is a maximal element c such that a∧c≤b. This binary operation is denoted a→b. A lattice with the pseudocomplement for each two elements is called implicative lattice, or Brouwerian lattice. In general, an implicative lattice may not have a minimal element.
More generally, in n-dimensional geometric algebra, pseudovectors are the elements of the algebra with dimension n − 1, written ⋀ n−1 R n. The label "pseudo-" can be further generalized to pseudoscalars and pseudotensors, both of which gain an extra sign-flip under improper rotations compared to a true scalar or tensor.
Individuals (instances) are the basic, "ground level" components of an ontology. The individuals in an ontology may include concrete objects such as people, animals, tables, automobiles, molecules, and planets, as well as abstract individuals such as numbers and words (although there are differences of opinion as to whether numbers and words are classes or individuals).
In abstract algebra, a congruence relation (or simply congruence) is an equivalence relation on an algebraic structure (such as a group, ring, or vector space) that is compatible with the structure in the sense that algebraic operations done with equivalent elements will yield equivalent elements.

Each skin has its own name as a class in the body element. These classes allow skin-specific print rules to be easily applied. Skin name is lowercase: skin-monobook, skin-modern etc. /includes/Skin.php: sortable Related to sortable tables — wikibits.js: sortarrow Related to sortable tables — wikibits.js: sortbottom
