The sign changes of Fourier coefficients of self-adjoint forms is an important area of research in number theory. Professor Yingnan Wang and his collaborators have made progress on two projects in this field.1.Paper Title：On the first sign change of Fourier coefficients of cusp formsProfessor Yingnan Wang, in collaboration with Associate Professor Guohua Chen of North China University of Water Resources ...
