Yang is mainly engaged in the research on complex analysis.In the 1970s, he made further study on the relation between deficient values and Borel directions of entire and meromorphic functions.Cooperated with Zhang Guanghou , he first discovered and established the detailed relation between these two basic concepts.He made further study on singular directions of meromorphic functions, introduced a new kind of singular directions and gave the perfect solution to the distribution of singular directions.He systematically studied the normality for families of holomorphic or meromorphic functions and established the relationship between the normality and fixed point.He and a British mathematician solved a conjecture posed by the exact estimation on the total deficiency of derivatives of meromorphic functions and the number of deficient values of entire functions.
