Let p be an odd prime. Define $e_{n}=\cases (-1)^{n+\overline{n}}, & \text{if}\ n\ \text{is a quadratic residue mod}\ p\,\\ (-1)^{n+\overline{n}+1}, & \text{if}\ n ...
If the nth term of a sequence is known, it is possible to work out any number in that sequence. Write the first five terms of the sequence \(3n + 4\). \(n\) represents the position in the sequence.
It is known (see [4, Brändén, Lemma 2.7]) that a necessary condition for 𝑇 := Σ 𝑄𝑘(𝑥)𝐷𝑘 to be hyperbolicity preserving is that 𝑄𝑘(𝑥) and 𝑄𝑘−1(𝑥) have interlacing zeros. We characterize all ...
