WebBounded volume hierarchy is a tree hierarchy that organizes a set of bounded volume objects into larger bounded volumes that can encompass one or more objects (Figure 3). The objects become leaf ... WebIn the first half of the twentieth century, some mathematicians (notably G. H. Hardy) believed that there exists a hierarchy of proof methods in mathematics depending on what sorts of numbers (integers, reals, complex) a proof requires, and that the prime number theorem (PNT) is a "deep" theorem by virtue of requiring complex analysis.
