WebJul 31, 2024 · To obtain the limit of average geodesic distances on growing Sierpinski networks, we obtain the accurate value of integral in terms of average geodesic distance and self-similar measure on the Sierpinski gasket. ... Li and H. Ruan, The “hot spots” conjecture on higher dimensional Sierpinski gaskets, Commun. Pure Appl. Anal. 15(1) … If we take n to be a negative integer, then the number k2 + 1 becomes $${\displaystyle {\frac {2^{ n }+k}{2^{ n }}}}$$. When k is odd, this is a fraction in reduced form, with numerator 2 + k. A dual Sierpinski number is defined as an odd natural number k such that 2 + k is composite for all natural … See more In number theory, a Sierpiński number is an odd natural number k such that $${\displaystyle k\times 2^{n}+1}$$ is composite for all natural numbers n. In 1960, Wacław Sierpiński proved that there are See more The Sierpiński problem asks for the value of the smallest Sierpiński number. In private correspondence with Paul Erdős, Selfridge conjectured that 78,557 was the smallest Sierpiński number. No smaller Sierpiński numbers have been discovered, and it is now … See more A number may be simultaneously Sierpiński and Riesel. These are called Brier numbers. The smallest five known examples are … See more The sequence of currently known Sierpiński numbers begins with: 78557, 271129, 271577, 322523, 327739, 482719, 575041, 603713, 903983, 934909, 965431, 1259779, 1290677, 1518781, 1624097, 1639459, 1777613, 2131043, 2131099, 2191531, … See more In 1976, Nathan Mendelsohn determined that the second provable Sierpiński number is the prime k = 271129.
