https://doi.org/10.1007/978-3-030-60094-5In the same way that the general notion of a group relates to transformation groups of an arbitrary set, finite groups relate to groups of transformations of a finite set; in this case, transformations are also called ..

Extending the Heron Metrics SinkWe now turn to the consideration of groups whose elements are given by continuously varying parameters; in other words, these are groups, occuring frequently in connection with questions of geometry or physics, whose set of elements itself has a geometry. This geometry may sometimes be very simple, but at other times far from trivial.

Clinical Features: Locally Defined Sites,Natural and important algebraic systems having all the properties of rings with the exception of the associativity of multiplication appeared very long ago, although the algebraic nature of these objects did not immediately become apparent.

The Algebraic View of Infinitesimal Notions,Considering quantities ‘up to infinitesimals of order .’ can be translated in algebraic terms quite conveniently, considering elements ε (of certain rings) satisfying ε. = 0 as analogues of infinitesimals. Suppose, for example, that . is an algebraic curve, for simplicity considered over the complex field ℂ.

Modules over Noncommutative Rings,A . over an arbitrary ring . is defined in the same way as in the case of a commutative ring: it is a set . such that for any two elements ., . ∈ ., the sum . + . is defined, and for . ∈ . and . ∈ . the product . ∈ . is defined, satisfying the following conditions (for all ., ., . ∈ . ∈ .).

The Notion of a Group,We start with the notion of a transformation group: the notion of a group first arose in this form, and it is in this form that it occurs most often in mathematics and mathematical physics.
