Abstract :Let f insert ignore into journalissuearticles values(z); — z co S n = 2 0 and g insert ignore into journalissuearticles values(z); — z — 00 s b. tt=2 bn —> 0. We investi- gate some properties of h insert ignore into journalissuearticles values(z); — f insert ignore into journalissuearticles values(z} 00 s wbere f insert ignore into journalissuearticles values(z); and g insert ignore into journalissuearticles values(z); n=2 satisfy either Reinsert ignore into journalissuearticles values(finsert ignore into journalissuearticles values(z); / z); Re insert ignore into journalissuearticles values(ginsert ignore into journalissuearticles values(z);/ z); ly. or Re £`« a for |z| 1.
