Authors: vahid reza morshedi , Mohammad Janfada ,
Full TextAbstract
In this paper, we develop the concept of dual and approximately dual frames in Banach spaces via semi-inner products and some properties of dual and approximate dual frames are investigated. Also, we introduce g-dual frames in these spaces and some relationships between g-duals and approximate duals are stated. Finally, the -nearly g-dual frames and their relations with g-duals are studied in Banach spaces using semi-inner products.
