The Duffin-schaeffer Conjecture with Extra Divergence
Throughout this note we will use the following standard notation from elementary number theory: p denotes a prime number, μ(n) is the Möbius function, φ(n) is the Euler phi function, ω(n) denotes the number of distinct prime divisors of n, and τ(n) is the number of positive integers which divide n. Also we use λ to denote Lebesgue measure on R/Z and dimX to denote the Hausdorff dimension of a s...
متن کاملThe Markoff-Duffin-Schaeffer inequalities abstracted.
The kth Markoff-Duffin-Schaeffer inequality provides a bound for the maximum, over the interval -1 </= x </= 1, of the kth derivative of a normalized polynomial of degree n. The bound is the corresponding maximum of the Chebyshev polynomial of degree n, T = cos(n cos(-1)x). The requisite normalization is over the values of the polynomial at the n + 1 points where T achieves its extremal values....

It is absurd and without any scientific interest to try to play off DES against EI, as if the question was to know if one method is better than the other in the absolute. All methodological inventions deserve to be tried and tested. But the question is how apposite are they to their object of study. However, Froese and Gould’s article opens a range of issues that are important and interesting. ...
متن کاملWalter Wunderlich ( 1910 – 1998 )
Walter Wunderlich was one of the most influential Austrian kinematicians in the 20th century. He wrote more than 200 scientific papers in the fields of mathematics, geometry and kinematics. Because of his influence, kinematic geometry is still an important subject in the curricula of geometry teachers’ education in Austria.

Antibiotics are widely used and their abuse has caused ecological hazard. Recently, pollution from pharmaceuticals and personal care products (PPCPs) has aroused great concern among governments and researchers. In order to elucidate the correlations among molecular structure, transmembrane distribution and toxicological effects of different kinds of antibiotics, zebrafish (Danio rerio) embryos ...
