“…It should be noted that as for the latter, what we observe is a sort of feedback: the term structure of interest rates is determined based on the prices of debt securities listed on the free market; on the other hand, it is the basis for pricing of such securities, which is particularly true for their new issuance. For this reason, bond pricing relies on highly advanced mathematical tools, such as non-linear approach methods [Deeba et al 2002], partial differential equations [Zui-Cha et al 2010], integration into trajectories known from the field of physics [Zanga et al 2017], and Green's function [Pooe et al 2004]. In the light of the aforementioned research, this paper relies on both elementary and deterministic methods.…”
