	PlanetMath: derivatives by pure algebra

	Wikinfo \| Derivation
		In abstract algebra, a derivation on an associative algebra A over a field k is a linear map D:A→A that satisfies Leibniz' law:
		Examples of derivations are partial derivatives, Lie derivatives, the Pincherle derivative, and the commutator with respect to an element of the algebra.
		Derivation may also be used as a synonym for proof, particularly for formulae.

		Points on the graph of a function where the derivative is undefined or equals zero are called critical points or sometimes stationary points (in the case where the derivative equals zero).
		In this case, the Second Derivative Test can still be used to characterize critical points, by considering the eigenvalues of the Hessian matrix of second partial derivatives of the function at the critical point.
		Perhaps the most natural situation is that of functions between differentiable manifolds; the derivative at a certain point then becomes a linear transformation between the corresponding tangent spaces and the derivative function becomes a map between the tangent bundles.

	Algebra -- from Wolfram MathWorld (via CobWeb/3.1 planetlab2.cs.virginia.edu) (Site not responding. Last check: 2007-11-02)
		One use of the word "algebra" is the abstract study of number systems and operations within them, including such advanced topics as groups, rings, invariant theory, and cohomology.
		This is the meaning mathematicians associate with the word "algebra." When there is the possibility of confusion, this field of mathematics is often referred to as abstract algebra.
		(Note that linear algebra, which is the study of linear sets of equations and their transformation properties, is not an algebra in the formal sense of the word.) Other more exotic algebras that have been investigated and found to be of interest are usually named after one or more of their investigators.

		In mathematics, the derivative of a function is one of the two central concepts of calculus.
		The Derivative of a function f at x is geometrically the slope of the tangent line to the graph of f at x.
		The Derivative is then defined by taking the limit of the slope of secant lines as they approach the tangent line.

		Lie algebra's are objects defined in abstract algebra(the theory of calculation).
		Now a Lie algebra is (the best known) an algebra which is non-associative, but of which the multiplication law satisfies the antisymmetry condition and the Jacobi associativity.
		Abstractly a Lie algebra is associated with derivations (or derivation operators).

	Exterior derivative - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-11-02)
		In mathematics, the exterior derivative operator of differential topology, extends the concept of the differential of a function to differential forms of higher degree.
		The exterior derivative of a differential form of degree k is a differential form of degree k + 1.
		and the Lie derivative of a general differential form is closely related to the exterior derivative.

		A von Neumann algebra is a strongly closed -subalgebra of the algebra* B(H) of bounded operators on a Hilbert space H. Equivalently, by virtue of the double commutant theorem, it is a *-subalgebra A of B(H) that is equal to its double commutant A^('').
		Then an algebra A is a local P-algebra provided that every finitely generated subalgebra F of A is a member of the class P.Note that classes P of algebras are identified with properties of algebras, so an algebra in the class P is said to be a
		Differential algebra is a field of mathematics that attempts to use methods from abstract algebra to study solutions of systems of polynomial nonlinear ordinary and partial differential equations.

		The representation is equivalent to that given by the action of G by linear substitution on the space of binary (i.e., 2 variable) quadratic forms.

	Berry Schoenmakers: PhD thesis
		Furthermore, a restricted type of algebras, called monoalgebras, is introduced, for which some theory is developed throughout the remainder of Part I. In Chapter 2, a notion of refinement is defined for monoalgebras.
		Our main reason for introducing a notion of algebra refinement is that it enables us to formulate a specification of a data structure as a quest for a concrete refinement of a given abstract algebra.
		In connection with this, two properties of algebras, called surjectivity and injectivity, are studied at the end of this chapter.

		(Note that "algebraic" here denotes something broader than high school algebra.) In formal logical systems, one is forced to state one's premises and rules of inference explicitly; and, given an explicit enough derivation for a conclusion, one can usually determine via syntactic inspection alone whether the reasoning is valid.

	Commutator information information - Search.com
		The subgroup generated by all commutators is called the derived group or the commutator subgroup of G.
		Note that one must consider the subgroup generated by the set of commutators because in general the set of commutators is not closed under the group operation.
		The commutator of two operators defined on a Hilbert space is an important concept in quantum mechanics since it measures how well the two observables described by the operators can be measured simultaneously.

	Product rule - Wikipedia, the free encyclopedia (via CobWeb/3.1 planetlab1.netlab.uky.edu) (Site not responding. Last check: 2007-11-02)
		This, combined with the sum rule for derivatives, shows that differentiation is linear.
		It is a common error, when studying calculus, to suppose that the derivative of (uv) equals (u′)(v′) (Leibniz himself made this error initially); however, it is quite easy to find counterexamples to this.
		In abstract algebra, the product rule is used to define what is called a derivation, not vice versa.
