This work discusses the role of relativity theory in modern astronomy and examines the conceptual and mathematical implications of discretizing continuous spacetime models. It explores whether astronomical phenomena can be modeled using discrete frameworks while remaining consistent with relativistic physics.
This monograph develops stochastic models for describing and analyzing populations composed of a large number of classes, with primary emphasis on biological communities and species diversity. The book introduces both fixed and random population models and examines sampling theory, abundance distributions, and indices of diversity and equitability. Classical models such as Fisher’s logarithmi…
