  2. Fundamental theorem of calculus - Wikipedia

    en.wikipedia.org/wiki/Fundamental_theorem_of...

    Intuitively, the fundamental theorem states that integration and differentiation are inverse operations which reverse each other. The second fundamental theorem says that the sum of infinitesimal changes in a quantity (the integral of the derivative of the quantity) adds up to the net change in the quantity. To visualize this, imagine traveling ...

  3. Fundamental theorems of welfare economics - Wikipedia

    Fundamental theorems of welfare economics. There are two fundamental theorems of welfare economics. The first states that in economic equilibrium, a set of complete markets, with complete information, and in perfect competition, will be Pareto optimal (in the sense that no further exchange would make one person better off without making another ...

    The Second Fundamental Theorem allows to give an upper bound for the characteristic function in terms of N(r,a). For example, if f is a transcendental entire function, using the Second Fundamental theorem with k = 3 and a 3 = ∞, we obtain that f takes every value infinitely often, with at most two exceptions, proving Picard's Theorem.

    In 1856, Clausius stated what he called the "second fundamental theorem in the mechanical theory of heat" in the following form: = where N is the "equivalence-value" of all uncompensated transformations involved in a cyclical process. This equivalence-value was a precursory formulation of entropy.

  6. Fundamental theorem of asset pricing - Wikipedia

    The Second Fundamental Theorem of Asset Pricing: Assume that there exists an equivalent local martingale measure . Then S {\displaystyle S} is a complete market if and only if Q {\displaystyle Q} is the unique local martingale measure.

  7. Integral - Wikipedia

    en.wikipedia.org/wiki/Integral

    In mathematics, an integral is the continuous analog of a sum, which is used to calculate areas, volumes, and their generalizations. Integration, the process of computing an integral, is one of the two fundamental operations of calculus, [a] the other being differentiation. Integration was initially used to solve problems in mathematics and ...

  8. Isomorphism theorems - Wikipedia

    en.wikipedia.org/wiki/Isomorphism_theorems

    In mathematics, specifically abstract algebra, the isomorphism theorems (also known as Noether's isomorphism theorems) are theorems that describe the relationship between quotients, homomorphisms, and subobjects. Versions of the theorems exist for groups, rings, vector spaces, modules, Lie algebras, and various other algebraic structures.

  9. Second law of thermodynamics - Wikipedia

    In 1865, the German physicist Rudolf Clausius stated what he called the "second fundamental theorem in the mechanical theory of heat" in the following form: [75] = where Q is heat, T is temperature and N is the "equivalence-value" of all uncompensated transformations involved in a cyclical process. Later, in 1865, Clausius would come to define ...
