The most key factor of this theorem is the principle that the when the sum of the two legs of a triangle added up‚ they are equal to the hypotenuse‚ longest side‚ of the right angled triangle. Meaning that whatever the numbers are on the legs of a triangle the sum will always give you the length of the third side of a triangle. In addition‚ to this theorem Pythagoras also discovered that a square is made of two triangles in which lead him to

levitation. In the past‚ magnetic levitation was attempted by using permanent magnets. Earnshaw’s theorem however‚ proves that this is mathematically impossible. There exists no arrangement of static magnets of charges that can stably levitate an object. There are however means of circumventing this theorem by altering its basic assumptions. The following conditions are exceptions to Earnshaw’s theorem: • Diamagnetism: occurs in materials which have a relative permeability less than one. The result

Algebra is one of the broad parts of mathematics‚ together with number theory‚ geometry and analysis. For historical reasons‚ the word "algebra" has several related meanings in mathematics‚ as a single word or with qualifiers. • As a single word without article‚ "algebra" names a broad part of mathematics (see below). • As a single word with article or in plural‚ "algebra" denotes a specific mathematical structure. See algebra (ring theory) and algebra over a field. • With a qualifier‚ there

treatment is unified in the sense that these probabilistic quantities are well defined for both ergodic and nonergodic Markov chains‚ and all results are valid for both approximation methods. Our proofs are simple in the sense that they only depend on one theorem from analysis: Weierstrass’ M-test. Our results include the convergence of stationary probability distributions when the Markov chain is ergodic. This work was directly motivated by the need to compute stationary probabilities for infinite-state Markov

Measures of Risk Aversion Financial Economics Martín Solá October 2010 Martín Solá (FE) Measures of Risk Aversion 08/10 1 / 41 Introduction In this …rst stage we will study the individual decisions of optimal portfolio choice under uncertainty and its consequences in the valuation of risky assets. In short‚ the Financial Theory rests on the no-arbitrage principle. The idea behind this principle is that it is not possible to make pro…ts without risk‚ without initial investment
