define a problem
41Rabi problem — The Rabi problem concerns the response of an atom to an applied harmonic electric field, with an applied frequency very close to the atom s natural frequency. It provides a simple and generally solvable example of light atom interactions.… …
42Is-ought problem — In meta ethics, the is ought problem was raised by David Hume (Scottish philosopher and historian, 1711 ndash;1776), who noted that many writers make claims about what ought to be on the basis of statements about what is . However, there seems to …
43Schottky problem — In mathematics, the Schottky problem is a classical question of algebraic geometry, asking for a characterisation of Jacobian varieties amongst abelian varieties.Geometric formulationMore precisely, one should consider algebraic curves C of a… …
44Trigonometric moment problem — In mathematics, the trigonometric moment problem is formulated as follows: given a finite sequence { α 0, ... αn }, does there exist a positive Borel measure mu; on the interval [0, 2 pi; ] such that:alpha k = frac{1}{2 pi}int 0 ^{2 pi} e^{… …
45Hilbert's third problem — The third on Hilbert s list of mathematical problems, presented in 1900, is the easiest one. The problem is related to the following question: given any two polyhedra of equal volume, is it always possible to cut the first into finitely many… …
46Orchard-planting problem — An arrangement of nine points forming ten 3 point lines. In discrete geometry, the original orchard planting problem asks for the maximum number of 3 point lines attainable by a configuration of points in the plane. Also called the Tree planting… …

48Series-parallel networks problem — In combinatorial mathematics, the series parallel networks problem asks for the number of series parallel networks that can be formed using a given number of edges. The edges can be distinguishable or indistinguishable.Indistinguishable edgesWhen …
49Mathematical formalization of the statistical regression problem — Although a rigorous formalization of the regression problem is not necessary in most cases, the theoretical study of the regression problem requires a precise mathematical context than that given in the Regression analysis… …
