Stability analysis of a mathematical model for the abatement of methane: Effect of mitigation options [PDF]

open access: yesComputational Ecology and Software, 2021
Atmospheric methane is one of the main greenhouse gases which contribute significantly to increase the burden of global warming. The production of rice paddies and livestock farming are the major sources of methane emissions in the atmosphere.

A Derivation of π(n) Based on a Stability Analysis of the Riemann-Zeta Function [PDF]

open access: yes, 2010
The prime-number counting function π(n), which is significant in the prime number theorem, is derived by analyzing the region of convergence of the real-part of the Riemann- Zeta function using the unilateral z-transform.

The equivalence ofB-stability andA-stability

open access: yesBIT, 1984
It is well known that linear and nonlinear stability concepts are equivalent for linear multistep methods in their one-leg formulation. This result is extended to Runge-Kutta methods. In particular, it is shown here that given an irreducible rational function R(z) whose degrees of numerator and denominator are at most s which has order of approximation
