Questions and Answers

What is the purpose of the modified mathematical model proposed by Cherniha R. and Davydovych V.?

  • To describe the competition and coexistence between speakers of different languages in Ukraine during the Soviet times.
  • To simplify the original model by introducing new constants k1, k2, k3, and k4. (correct)
  • To replace the fractional nonlinearity in the original model with logistic terms.
  • To solve the system of nonlinear fractional equations analytically.

    • What is the purpose of replacing the fractional nonlinearity $\frac{p}{p+q+s}$, $\frac{q}{p+q+s}$, and $\frac{s}{p+q+s}$ with the constants k1, k2, and k3, respectively?

  • To restrict the unbounded growth of the language communities.
  • To introduce additional complexity to the model.
  • To make the system of equations easier to solve analytically. (correct)
  • To make the system of equations more difficult to solve analytically.

    • What is the relationship between the variables p, q, s, and n in the simplified system of equations?

  • They are related through the fractional nonlinearity, but not linearly.
  • They are independent variables.
  • They are linearly related, with p = k1(p+q+s), q = k2(p+q+s), s = k3(p+q+s), and n = k4n. (correct)
  • They are related through the logistic terms, but not linearly.
