Abstract
In this paper, we first prove a theorem by a little modification on the Lax-Milgram theorem. Then, using -frames, we obtain lower and upper bounds for the results obtained from this theorem. Also, we present some methods for the characterization of scalable -frames. Finally, we introduce piecewise scalable -frames and give necessary and sufficient conditions for a -frame to be piecewise scalable.
