New Schweizer Sklar Norm Picture Fuzzy Operator and Decision Application [PDF]
Jisuanji gongcheng, 2023 Existing picture fuzzy operational laws do not satisfy the closure and picture fuzzy aggregation operators, mostly aggregating the evaluation information through a single operator, which interferes with the comprehensive consideration of the relationship

A more accurate Mulholland-type inequality in the whole plane
Journal of Inequalities and Applications, 2017 By introducing independent parameters, applying the weight coefficients, and Hermite-Hadamard’s inequality, we give a more accurate Mulholland-type inequality in the whole plane with a best possible constant factor. Furthermore, the equivalent forms, the

The Krein-von Neumann extension of a regular even order quasi-differential operator [PDF]
Opuscula Mathematica, 2021 We characterize by boundary conditions the Krein-von Neumann extension of a strictly positive minimal operator corresponding to a regular even order quasi-differential expression of Shin-Zettl type.
