Fuzzy Logical Algebra and Study of the Effectiveness of Medications for COVID-19

A fuzzy logical algebra has diverse applications in various domains such as engineering, economics, environment, medicine, and so on. However, the existing techniques do not apply to delta-algebra. Therefore, purpose of this paper was investigate new types cubic soft algebras study their applications, representation sets with δ-algebras, algebras, δ-subalgebra based on parameter λ (λ-CSδ-SA) (CSδ-SA) over η. This explains why P-union is really a two δ-subalgebras. We also reveal that any R/P-cubic subsets necessarily (CSδ-SA). Furthermore, we present required conditions prove R-union members if each one them To illustrate our assumptions, proposed applied effectiveness medications for COVID-19 using python program.
