*unsolved mathematical mysteries*

*since the ‘renaissance’, every century has seen the solution of more mathematical problems than the century before, and yet many mathematical problems, both major and minor, still remain unsolved*

(prizes are often awarded for the solution to a long-standing problem, and lists of unsolved problems (such as the list of Millennium Prize Problems) receive considerable attention)

(unsolved problems remain in multiple domains, including…

physics

computer science

algebra,

additive and algebraic number theories,

analysis,

combinatorics,

algebraic, discrete and euclidean geometries,

graph, group, model, number, set and ramsey theories,

dynamical systems,

‘partial differential equations’,

‘miscellaneous unsolved problems’
