Random coefficient differential models of growth of anaerobic photosynthetic bacteria

Dan Stanescu, Benito Chen-Charpentier, Brandi J. Jensen, and Patricia J. S. Colberg


In many fields of science and engineering there are mathematical models given in terms of differential equations with random coefficients. The randomness is due to errors or uncertainty. Closed solutions are few, and usually numerical approximations need to be calculated. Polynomial chaos is a powerful method in this regard. Here we apply this method to several modeling approaches for the time evolution of photosynthetic bacterial populations. Usual methods used in microbiology are contrasted with approaches based on differential equations with random coefficients. Numerical results based on laboratory data for two different species of bacteria are presented.
