Bridging Quasilinear and Bilinear Operators with Soft Operator Theory via Soft Biquasilinear Mappings

Abstract

In this paper, the relationship between soft bilinear operators and classical bilinear operators is illustrated using an example. We then introduce soft biquasilinear operators, which extend the concept of classical biquasilinear operators to the soft setting. Several soft biquasilinear operators are examined, leading to important findings. In addition, as in classical functional analysis, we observe that every soft quasilinear inner product gives rise to a soft biquasilinear operator. Moreover, the relationships among these operators are summarized in a small table. We denote the set of all soft biquasilinear functions by Λ(Q ̃^2,(Ω_C (R)) ̃), and we show that when equipped with a suitably defined norm, this set forms a soft normed quasilinear space and, moreover, a Banach quasilinear space. Additionally, the symmetry and positivity of soft biquasilinear operators are analyzed, and several related theorems are established, thereby providing a solid foundation for further developments in soft operator theory and soft functional analysis. These results demonstrate the advantages and applicability of the soft framework, thereby laying the foundation for further theoretical developments and practical applications.
