Prof. Alexander Zino-view, in trouble after publishing a statistical novel in the West, said yesterday that Soviet authorities were unempectedly allowing him to travel abroad.

Zinoview, 56, told reporters by telephone that he and his family had been given permission to accept an invitation to take up a post at Munich University. His original application was rejected six months ago.

"It came as a complete surprise," he said.

His novel "The Yawning Heights," which apparently satirizes the Soviet Union, was publized in the West last year and this led to his swift dismissal from his job at the Soviet Academy of Sciences.

Zinoview expected to leave for West Germany next month with his wife, Ogla, and daughter, Polina.

A former professor of logic at Moscow University, he first applied to take up the Munich position in May last year.

In other developments involving Soviet dissidents:

The mother of convicted dissident Anatoly Scharansky was allowed to see him yesterday for the first time since his arrest 16 months ago, sources said. Ida Milgrom, 70, reportedly broke down and cried when officials at Moscow's Lefortova prison refused to let her give her son food that she brought with her. The two were permitted to talk for 25 minutes.
