Analysis of ecological territorial risk by methods of multidimensional statistics
В работе рассмотрены водные экосистемы как элементы единой социально природно-техногенной системы, предлагаемой для решения задач управления развитием промышленных территорий. Для оценки территориальных рисков водных ...
Some recent fixed point results of F-contractive mappings in metric space
The opinion is that the most important result in the metrical theory of
fixed points is the famous Banach contraction principle from 1922. It has been
generalized and extended in several directions. One of the most ...
Complex homogeneous differential equation of first and second order through iterations
The theory of complex differential equations represents an important mathematical discipline both from the theoretical point of view and from numerous applications. Its development was equally encouraged by mathematicians, ...
Number of zero solutions of some canonical complex differential equations of second order with variable coefficient
By solving the frequency function equation only a small number of complex equations of the second order oscillations can be solved. The simplest way is to observe canonical complex differential equations with constant ...
Zero search method for complex oscillating equation directly by direction
The problem of location of the zero solution of the second order complex oscillator equation for the given analytic function is unlikely to be completely solved. Therefore, estimates have long been resorted to. The easiest ...
The second mean value theorem for complex line integral
In real iterations, several types of mean value theorems for definite integrals are used. In complex domain, we cannot specifically formulate the mean value theorem of a particular complex line integral (L) ∫f(z)dz , since ...
