In this paper, we have proved the existence and uniqueness of almost non-negative periodic solution to a class of generalized Sine-Gordon equation. The main method used is the maximum principle of telegraph equation established by Mawhin, Ortega and Robles-Pérez. The main techniq...

The golden cut divides a line so that the ratio between the long and the short leg equals the ration between the sum of the two legs and the long leg. Surprisingly, the value for this ratio can be approached by dividing increasing neighboring Fibonacci numbers, numbers where the...

Copulas are mathematical objects that fully capture the dependence structure among random variables and thus offer a great deal of flexibility in building multivariate stochastic models. They have widely use in, credit models, risk aggregation, portfolio selection, insurance, and...

Aims/Objectives: We propose a dual method of Carroll's generalized canonical correlation analysis and we prove by means of the proposed criterion that the duality is formulated by exchanging the operators. It is an extension of Carroll's generalized canonical correlation analysis...

When the eigenvalue \(\lambda\) of a higher order homogeneous linear differential equation with constant coecients is the repeated root of multiplicity \(k\), the differential equation has exactly \(k\) linearly independent solutions. Different textbooks often use different ways...

When data are found to be realizations of a specific distribution, constructing the probability density function based on this distribution may not lead to the best prediction result. In this study, numerical simulations are conducted using data that follow a normal distribution,...

Numerical analysis of fluid flow is anchored on the laws of conservation. A challenge in solving the momentum equation arises due to the unavailability of an explicit pressure equation. To avoid solving the pressure term most researchers have eliminated it by cross differentiatin...
