Moduli spaceIn mathematics, in particular algebraic geometry, a moduli space is a geometric space (usually a scheme or an algebraic stack) whose points represent algebro-geometric objects of some fixed kind, or isomorphism classes of such objects. Such spaces frequently arise as solutions to classification problems: If one can show that a collection of interesting objects (e.g., the smooth algebraic curves of a fixed genus) can be given the structure of a geometric space, then one can parametrize such objects by introducing coordinates on the resulting space.
Upper classUpper class in modern societies is the social class composed of people who hold the highest social status, usually are the wealthiest members of class society, and wield the greatest political power. According to this view, the upper class is generally distinguished by immense wealth which is passed on from generation to generation. Prior to the 20th century, the emphasis was on aristocracy, which emphasized generations of inherited noble status, not just recent wealth.
Social inequalitySocial inequality occurs when resources in a given society are distributed unevenly, typically through norms of allocation, that engender specific patterns along lines of socially defined categories of persons. It poses and creates a gender gap between individuals that limits the accessibility that women have within society. The differentiation preference of access to social goods in the society is brought about by power, religion, kinship, prestige, race, ethnicity, gender, age, sexual orientation, and class.
Ethnic violenceEthnic violence is a form of political violence which is expressly motivated by ethnic hatred and ethnic conflict. Forms of ethnic violence which can be argued to have the characteristics of terrorism may be known as ethnic terrorism or ethnically motivated terrorism. "Racist terrorism" is a form of ethnic violence which is dominated by overt racism and xenophobic reactionism. Ethnic violence which is perpetrated in an organized, sustained form is known as ethnic conflict or ethnic warfare (race war), in contrast to class conflict, where the dividing line is social class rather than ethnic background.
Hate crimeA hate crime (also known as a bias-motivated crime or bias crime) is a prejudice-motivated crime which occurs when a perpetrator targets a victim because of their membership (or perceived membership) of a certain social group or racial demographic. Examples of such groups can include, and are almost exclusively limited to ethnicity, disability, language, nationality, physical appearance, political views and/or affiliation, age, religion, sex, gender identity, or sexual orientation.
