Wolfram. They Tried to Outsmart Wall Street. Basics - Gut Instinct’s Surprising Role in Math. Tikhonov regularization. When the following problem is not well posed (either because of non-existence or non-uniqueness of where may be ill-conditioned or singular).

Tikhonov regularization

In the latter case this is no better than the original problem. In order to give preference to a particular solution with desirable properties, the regularization term is included in this minimization: for some suitably chosen Tikhonov matrix, . , is given by: TNT Home Page. An Intuitive Explanation of Fourier Theory. Steven Lehar Fourier theory is pretty complicated mathematically. But there are some beautifully simple holistic concepts behind Fourier theory which are relatively easy to explain intuitively. Annals of Mathematics: Manifold Destiny. On the evening of June 20th, several hundred physicists, including a Nobel laureate, assembled in an auditorium at the Friendship Hotel in Beijing for a lecture by the Chinese mathematician Shing-Tung Yau.

Annals of Mathematics: Manifold Destiny

In the late nineteen-seventies, when Yau was in his twenties, he had made a series of breakthroughs that helped launch the string-theory revolution in physics and earned him, in addition to a Fields Medal—the most coveted award in mathematics—a reputation in both disciplines as a thinker of unrivalled technical power. Yau had since become a professor of mathematics at Harvard and the director of mathematics institutes in Beijing and Hong Kong, dividing his time between the United States and China. His lecture at the Friendship Hotel was part of an international conference on string theory, which he had organized with the support of the Chinese government, in part to promote the country’s recent advances in theoretical physics.

Then n = 16 + 42*k is a failure function ). [P] Failure functions - role of by akdevarajApr 13 failure functions play an important role in proving a conjecture indirectly. See sketch proof. [P] failure functions - another example by akdevarajApr 12 Here k belongs to N.When n= 10, f(n) = 1105, a Carmichael number; however when n is generated by the failure function 18 + 20*k we get values of f(n) which are not square free and hence incapable of being Carmichael numbers i.e. failures.

Golden ratio - Wikipedia, the free encyclo. Line segments in the golden ratio In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.

Golden ratio - Wikipedia, the free encyclo

The figure on the right illustrates the geometric relationship. Expressed algebraically, for quantities a and b with a > b > 0, The golden ratio is also called the golden section (Latin: sectio aurea) or golden mean.[1][2][3] Other names include extreme and mean ratio,[4] medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut,[5] and golden number.[6][7][8] Geometric Paper Folding: Dr. David Huffman. Nov 1996 David Huffman has been creating some very complex and original folded structures.

He works with both straight and curved folds, using mathematical techniques that he has developed over many years. Mr. Huffman teaches at the University of California at Santa Cruz.
