Asymmetry is the absence of, or a violation of, symmetry (the property of an object being invariant to a transformation, such as reflection). [1] Symmetry is an important property of both physical and abstract systems and it may be displayed in precise terms or in more aesthetic terms. [ 2 ]
Asymmetric warfare (or asymmetric engagement) is a type of war between belligerents whose relative military power, strategy or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents , terrorist groups , or resistance militias operating within territory mostly controlled by the superior force.

Symmetry breaking occurs at several different levels in order to generate the anatomical asymmetry which we observe. These levels include asymmetric gene expression, protein expression, and activity of cells. For example, left–right asymmetry in mammals has been investigated extensively in the embryos of mice. Such studies have led to support ...
An asymmetric relation need not have the connex property. For example, the strict subset relation is asymmetric, and neither of the sets {,} and {,} is a strict subset of the other. A relation is connex if and only if its complement is asymmetric.
An asymmetric cell division produces two daughter cells with different cellular fates. This is in contrast to symmetric cell divisions which give rise to daughter cells of equivalent fates. Notably, stem cells divide asymmetrically to give rise to two distinct daughter cells: one copy of the original stem cell as well as a second daughter ...
This type of asymmetry can be called de jure asymmetry (Brown 2). The second type reflects agreements which come out of national policy, opting out, and (depending on one's definition of the term) bilateral and ad hoc deals with specific provinces, none of which are entrenched in the constitution. This type of asymmetry is known as de facto ...
In contract theory, mechanism design, and economics, an information asymmetry is a situation where one party has more or better information than the other. Information asymmetry creates an imbalance of power in transactions, which can sometimes cause the transactions to be inefficient, causing market failure in the worst case.
