Longer than Average Intervals Containing No Primes
نویسنده
چکیده
We present two methods for proving that there is a positive proportion of intervals which contain no primes and are longer than the average distance between consecutive primes. The first method is based on an argument of Erdös which uses a sieve upper bound for prime twins to bound the density function for gaps between primes. The second method uses known results about the first three moments for the distribution of intervals with a given number of primes. Better results are obtained by assuming that the first n moments are Poisson. The related problem of longer than average gaps between primes is also considered.

Motor control in old age: evidence of impaired low-level inhibition.
In the masked prime task, responses to supraliminal targets are influenced by previously presented subliminal primes. When targets follow primes immediately, positive compatibility effects are obtained such that performance is better when prime and target are compatible (mapped to the same response) than when they are incompatible (mapped to opposite responses). In young adults, this pattern re...
متن کاملOn Small Intervals Containing Primes
Let p be an odd prime, such that pn < p/2 < pn+1, where pn is the n-th prime. We study the following question: with what probability does there exist a prime in the interval (p, 2pn+1)? After the strong definition of the probability with help of the Ramanujan primes ([11], [12])and the introducing pseudo-Ramanujan primes, we show, that if such probability P exists, then P ≥ 0.5. We also study a...
متن کاملOn the symmetry of primes in almost all short intervals
– In this paper we study the symmetry of primes in almost all short intervals; by elementary methods (based on the Large Sieve) we give, for h x log x (c > 0, suitable), a non-trivial estimate for the mean-square (over N < x ≤ 2N) of an average of “symmetry sums”; these sums control the symmetry of the von-Mangoldt function in short intervals around x. We explicitly remark that our results are ...
متن کاملHomophonic and semantic priming of Japanese Kanji words: a time course study.
In an examination of the time course of activation of phonological and semantic information in processing kanji script, two lexical decision experiments were conducted with native readers of Japanese. Kanji targets were preceded at short (85-msec) and long (150-msec) intervals by homophonic, semantically related, or unrelated primes presented in kanji (Experiment 1) or by hiragana transcription...
متن کاملHigher Correlations of Divisor Sums Related to Primes Iii: Small Gaps between Primes
We use divisor sums to approximate prime tuples and moments for primes in short intervals. By connecting these results to classical moment problems we are able to prove that, for any η > 0, a positive proportion of consecutive primes are within 4 + η times the average spacing between primes. Authors’ note. This paper was written in 2004, prior to the solution, in [8], of the problem considered ...
