WebHilbert’s third problem asked to produce two polyhedra of equal volume which are not scissors congruent. In 1901 Dehn showed that a second invariant, now called the Dehn invariant, was preserved under such decompositions, and that this invariant is zero for the cube but nonzero for the regular tetrahedron, thus providing the example Hilbert ...

WebJan 24, 2024 · In this article, a novel quad-band fractal PIFA antenna design for DCS, PCS, UMTS, and WiMAX wireless communications systems is presented. The proposed antenna is a PIFA antenna where a slot having a Hilbert fractal shape at the third iteration has been inserted at the center of the radiating patch. The fractal shape of the implanted slot on the … The third of Hilbert's list of mathematical problems, presented in 1900, was the first to be solved. The problem is related to the following question: given any two polyhedra of equal volume, is it always possible to cut the first into finitely many polyhedral pieces which can be reassembled to yield the second? … See more The formula for the volume of a pyramid, $${\displaystyle {\frac {{\text{base area}}\times {\text{height}}}{3}},}$$ had been known to Euclid, but all proofs of it involve some form of limiting process or calculus, … See more Dehn's proof is an instance in which abstract algebra is used to prove an impossibility result in geometry. Other examples are See more Hilbert's original question was more complicated: given any two tetrahedra T1 and T2 with equal base area and equal height (and therefore equal volume), is it always possible to find a finite number of tetrahedra, so that when these tetrahedra are glued in some … See more • Proof of Dehn's Theorem at Everything2 • Weisstein, Eric W.
