The example shows that the approach can overcome imprecision of max-operator and min-operator used during the process of fuzzy reasoning. Therefore, the information accuracy and the system performance can be effectively improved, which promotes the usability of FuzzyJ Toolkit.展开更多

Thepaper contains two parts. The first part shows that the commutant ideal I(T) of C(T) is*isomorphic to where ?_n ??_(n+1), n = 1,2,…and ?_n is * isomorphic to the n-matrix algebra over C_0(Z_0). In particular, when T is a completely nonnormal strong Θ-operator, I(T) is * isomorphic to C_0(Z_0)(×)K(I^2). The second part gives the equivalent con-ditions which make the spectrum and the approximate spectrum of the completely nonnormalstrong Θ-operator identify and some K-groups of the C-algebra generated by this classoperator are computed in this part.展开更多

We have, for example, electromagnetic waves with the photon as the corresponding particle, gravitational waves with the graviton as the corresponding particle, and Dirac waves with the electron as the corresponding particle. All these theories are stand-alone theories having nothing in common. The outstanding problem is a unified theory of particles and fields. In this paper, we discuss a unified geometrical theory of fields and particles.展开更多

A dendriform algebra is a J-dendriform algebra. Moreover, J-dendriform algebras fit into a commutative diagram which extends the relationships among associative, Lie, and Jordan algebras. Their relations with some structures such as Rota-Baxter operators, classical Yang-Baxter equation, and bilinear forms are given.展开更多
