  2. Utility maximization problem - Wikipedia

    en.wikipedia.org/wiki/Utility_maximization_problem

    The income effect occurs when the change in prices of goods cause a change in income. If the price of one good rises, then income is decreased (more costly than before to consume the same bundle), the same goes if the price of a good falls, income is increased (cheeper to consume the same bundle, they can therefore consume more of their desired ...

  3. List of unsolved problems in mathematics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.

  4. 3x + 1 semigroup - Wikipedia

    en.wikipedia.org/wiki/3x_+_1_semigroup

    The 3x + 1 semigroup has been used to prove a weaker form of the Collatz conjecture. In fact, it was in such context the concept of the 3 x + 1 semigroup was introduced by H. Farkas in 2005. [ 2 ] Various generalizations of the 3 x + 1 semigroup have been constructed and their properties have been investigated.

  5. Lagrange multiplier - Wikipedia

    en.wikipedia.org/wiki/Lagrange_multiplier

    In mathematical optimization, the method of Lagrange multipliers is a strategy for finding the local maxima and minima of a function subject to equation constraints (i.e., subject to the condition that one or more equations have to be satisfied exactly by the chosen values of the variables). [1]

  6. Corner solution - Wikipedia

    en.wikipedia.org/wiki/Corner_solution

    IC 1 is not a solution as it does not fully utilise the entire budget, IC 3 is unachievable as it exceeds the total amount of the budget. The optimal solution in this example is M units of good X and 0 units of good Y. This is a corner solution as the highest possible IC (IC 2) intersects the budget line at one of the intercepts (x-intercept). [1]

  7. Millennium Prize Problems - Wikipedia

    en.wikipedia.org/wiki/Millennium_Prize_Problems

    More specifically, the Millennium Prize version of the conjecture is that, if the elliptic curve E has rank r, then the L-function L(E, s) associated with it vanishes to order r at s = 1. Hilbert's tenth problem dealt with a more general type of equation, and in that case it was proven that there is no algorithmic way to decide whether a given ...

  8. Slutsky equation - Wikipedia

    en.wikipedia.org/wiki/Slutsky_equation

    This says that when rises, there is a substitution effect of / towards good 1. At the same time, the rise in has a negative income effect on good 1's demand, an opposite effect of the same size as the substitution effect, so the net effect is zero. This is a special property of the Cobb-Douglas function.

  9. Problem-based learning - Wikipedia

    en.wikipedia.org/wiki/Problem-based_learning

    Problem-based learning has subsequently been adopted by other medical school programs [5] adapted for undergraduate instruction, [6] [7] [8] as well as K-12. [ 5 ] [ 9 ] The use of PBL has expanded from its initial introduction into medical school programs to include education in the areas of other health sciences , math , law , education ...
