Abstract: |
This paper is devoted to studying a singular fractional Trudinger-Moser inequality in dimension one. By the Green representation formula for functions in the fractional Sobolev spaces, we get a singular fractional Trudinger-Moser type inequality. Furthermore, by using a suitable test functions sequence, we can show that the constant in the inequality is optimal. This result extends the singular Trudinger-Moser inequality in the high-dimensional spaces to the space of dimension one. |
