The influence exerted by the second time derivative with a small parameter added to the heat equation in the case of discontinuous periodic initial data is investigated. It is shown that, except for the initial instants of time, the error of hyperbol

A modified two-dimensional two-phase mathematical model of forest wildfires propagation is considered. The model is based on the averaging of three-dimensional equations of two-phase medium over the height of the forest fuel (FF) layer and it include

A two-dimensional three-phase mathematical model of forest fires is considered. The model is based on the averaging of initial multiphase medium equations over the height of the forest fuel (FF) layer. The developed model can be used to carry out num

The classical Godunov scheme for the numerical solution of 3D gas dynamics equations is justified in the multidimensional case. An estimate is obtained for the error induced by replacing the exact solution of the multidimensional discontinuity breaku

The difference between the solutions of the heat equation and its hyperbolized version is estimated. The estimates are obtained in the L2 norm for the anisotropic heat equation and in the C norm for the one-dimensional case with constant coefficients

A two-dimensional three-phase mathematical model of forest fires constructed by the method of averaging over the height of the forest fuel layer is considered. The gas phase in the model is described by gas dynamics equations with the k − ε turbul

The effective dimension of a multidimensional function was previously introduced to measure the complexity of the function with respect to the evaluation of an integral by quasi-Monte Carlo methods. For the same goal, the concept of the average dimen
