Geometric perspectives on angles in n-inner product spaces

M. Nur, S. Konca

In this work, we explore the angles between vectors and subspaces within the framework of standard n-inner product spaces, focusing initially on finite-dimensional cases. We delve into the connections with angles on inner product spaces. Furthermore, we extend our analysis to encompass infinite-dimensional n-inner product spaces, providing a comprehensive understanding of angular relationships in both finite and infinite dimensions.
