Of the cleanly formulated Hilbert problems, numbers 3, 7, 10, 14, 17, 18, 19, 21, and 20 have resolutions that are accepted by consensus of the mathematical community. Problems 1, 2, 5, 6, [ a ] 9, 11, 12, 15, and 22 have solutions that have partial acceptance, but there exists some controversy as to whether they resolve the problems.
While a system of 3 bodies interacting gravitationally is chaotic, a system of 3 bodies interacting elastically is not. [clarification needed] There is no general closed-form solution to the three-body problem. [1] In other words, it does not have a general solution that can be expressed in terms of a finite number of standard mathematical ...
Dehn's proof is an instance in which abstract algebra is used to prove an impossibility result in geometry.Other examples are doubling the cube and trisecting the angle.. Two polyhedra are called scissors-congruent if the first can be cut into finitely many polyhedral pieces that can be reassembled to yield the second.
In the basic assignment problem, each agent is assigned to at most one task and each task is assigned to at most one agent. In the many-to-many assignment problem, [10] each agent i may take up to c i tasks (c i is called the agent's capacity), and each task j may be taken by up to d j agents simultaneously (d j is called the task's capacity).
Tarski's circle-squaring problem is the challenge, posed by Alfred Tarski in 1925, [1] to take a disc in the plane, cut it into finitely many pieces, and reassemble the pieces so as to get a square of equal area.
The Basel problem is a problem in mathematical analysis with relevance to number theory, concerning an infinite sum of inverse squares.It was first posed by Pietro Mengoli in 1650 and solved by Leonhard Euler in 1734, [1] and read on 5 December 1735 in The Saint Petersburg Academy of Sciences. [2]
There are 2 7825 ≈ 3.63×10 2355 possible coloring combinations for the numbers up to 7825.These possible colorings were logically and algorithmically narrowed down to around a trillion (still highly complex) cases, and those, expressed as Boolean satisfiability problems, were examined using a SAT solver.
In classical mechanics, the Kepler problem is a special case of the two-body problem, in which the two bodies interact by a central force that varies in strength as the inverse square of the distance between them.
