The XSL Formatting Objects (XSL-FO) specification was designed from the start to be locale and language neutral. This makes XSL-FO well suited to the task of composing for print internationalized documents, and in particular, documents in non-Western languages. However, users of XSL-FO are dependent on both the implementation of XSL-FO internationalization features, such as support for differen...

in this paper we introduce and study besselian $g$-frames. we show that the kernel of associated synthesis operator for a besselian $g$-frame is finite dimensional. we also introduce $alpha$-dual of a $g$-frame and we get some results when we use the hilbert-schmidt norm for the members of a $g$-frame in a finite dimensional hilbert space.
