They belong to different areas of mathematics, number theory, Diophantine equations, complex analysis, graph theory, and complexity theory. Assertions state positive facts or negative results; some are very old, and others are relatively new.#Surprisingly enough, such a "commonality" exists for many...

Love also contributed to the theory of tidal locking and introduced the parameters known as Love numbers, which are widely used today. These numbers are also used in problems related to the tidal deformation of the Earth due to the gravitational attraction of the Moon and Sun. He w...
Or in graph theory we know BFS, DFS< Dijkstra , MST, Eular trail/circuit and many more. As a beginner I have learned those famous techniques and many variation by solving problems on different oj. But now I see that a difficult problem have been appeared , though I have learned this to...
prices will crash and the bubble proponents will be proven right in the long run. So most people would implicitly think; “Why praise someone for being right for the wrong reason?” Of course this makes bubble theory into a near tautology, irrefutable in volatile asset markets that will almos...
