Alphonse de Polignac (1826–1863) was a French mathematician. In 1849, the year he was admitted to Polytechnique, he made what's known as Polignac's conjecture:[1]
- For every positive integer k, there are infinitely many prime gaps of size 2k.
The case k = 1 is the twin prime conjecture.
He also conjectured Romanov's theorem.
His father, Jules de Polignac (1780-1847) was prime minister of Charles X until the Bourbon dynasty was overthrown (1830).
