Identification of mathematical models of reduced reaction scheme

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2009
The authors have developed the algorithm to solve an inverse problem for the reduced reaction schemes which allows determining kinetic parameters of reaction schemes with smaller dimension preserving dynamics of concentration target substances. The mathematical model of the reduced scheme of α-methylstyrene dimerization was identified.

25 Years of Quantum Groups: from Definition to Classification

open access: yesActa Polytechnica, 2008
In mathematics and theoretical physics, quantum groups are certain non-commutative, non-cocommutative Hopf algebras, which first appeared in the theory of quantum integrable models and later they were formalized by Drinfeld and Jimbo.

Convergence of numerical methods for stochastic differential equations in mathematical finance

open access: yes, 2012
Many stochastic differential equations that occur in financial modelling do not satisfy the standard assumptions made in convergence proofs of numerical schemes that are given in textbooks, i.e., their coefficients and the corresponding derivatives ...

Research on the ratio of similar materials in water-absorbent mudstone based on fuzzy mathematics

open access: yesScientific Reports
To determine the suitability and credibility of similar water-absorbent mudstone materials in model experiments, the prototype mudstone parameter similarity index was determined based on the similarity theory.
