In the domain of artificial neural networks, it is important to know what their representation, classification and generalization capabilities are. There is also a need for time and resource-efficient training algorithms. Here, a new zero-error train

In recent years, complex-valued fuzzy metric spaces (in short CVFMS) were introduced by Shukla et al. (Fixed Point Theory 32 (2018)). This setting is a valuable extension of fuzzy metric spaces with the complex grade of membership function. They also

The concept of residuated relational systems ordered under a quasi-order relation was introduced in 2018 by S. Bonzio and I. Chajda. In such algebraic systems, we have introduced and developed the concepts of implicative and comparative filters. In a

Let $${\mathfrak {X}}$$ be a class of simple groups with a completeness property $$\pi ({\mathfrak {X}}) = \mathrm {char} \, {\mathfrak {X}}$$ . A formation is a class of finite groups closed under taking homomorphic images and finite subdirect produ

The paper concerns global solvability of initial value problem for one class of hyperbolic quasilinear second order equations with two independent variables, which have a rather wide range of applications. Besides existence and uniqueness of maximal

We consider a three-dimensional equation of elliptic type with two singular coefficients, for which the Dirichlet problem is studied in a half-cylinder. The study of the problem is carried out using the method of spectral analysis. For the problem po

We prove a global uniqueness result for the Calderon inverse problem for a general quasilinear isotropic conductivity equation on a bounded open set with smooth boundary in dimension n ≥ 3 . Performing higher order linearizations of the nonlinear D

The diagonalization argument is one way that researchers use to prove the set of real numbers is uncountable. In the present paper, we prove the same thing by using the supremum property in the set of real numbers.
