Characterizations of harmonic quasiregular mappings in function spaces

Jihua Sun, Junming Liu, Zhi-Gang Wang

We study conjugate-type phenomena for complex-valued harmonic quasiregular mappings in the unit disk across three function space families: $Q (n, p, I^\pm)$ , $F (p, q, s)$ , and the non-deri…

Multiplicative operators on analytic function spaces

Kanha Behera, Junming Liu, P. Muthukumar

H. J. Schwartz proved in his thesis (1969) that a nonzero bounded operator on Hardy spaces $(H^{p}, 1 \leq p \leq \infty)$ is almost multiplicative if and only if it is a composition op…
