It is relevant in problems of physics and has number theoretic significance. In particular, according to the prime number theorem, it is a very good approximation to the prime-counting function,…","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400,"thumbnail_url":"https://thumb.wikimedia.org/wikipedia/commons/thumb/3/33/Plot_of_the_logarithmic_integral_function_li%28z%29_in_the_complex_plane_from_-2-2i_to_2%2B2i_with_colors_created_with_Mathematica_13.1_function_ComplexPlot3D.svg/1280px-Plot_of_the_logarithmic_integral_function_li%28z%29_in_the_complex_plane_from_-2-2i_to_2%2B2i_with_colors_created_with_Mathematica_13.1_function_ComplexPlot3D.svg.png","thumbnail_width":1280,"thumbnail_height":1146}
