Carry forward of losses on transfer of public limited company ?

Transfer of ownership i.e. transfer of share of  Closely held company attracts sec. 79 for carry forward & Set off of Losses & unabsorbed depreciation. It also lays down condition of Minimum 51% share holding to remain intact & lock in period for it.

BUT what in respect of Public company?

Can Losses be carried forward & set off on transfer of ownership of public company? Mostly when more than 51% of share holding is transfered to outsiders?

What are the ways by which losses can be c/f & ownership stands transfered ?

Please answer if such losses can be carried forward? Please specify relevant provisions if Any??
