On the Irrationality Measure of ln 7
I. V. Bondareva, M. Yu. Luchin, Владислав Хасанович Салихов · Mathematical Notes · 2020
Using an integral construction based on symmetrized polynomials, we obtain a new estimate for the irrationality measure of the number In 7. This estimate improves a result due to Wu, which was proved in 2002.
