Some of his key works include:
* "Spatial Variation" (1960): This book lays out the foundations of stochastic geometry and introduces the Poisson point process as a tool for analyzing spatial data.
* "The Hard Core Model: A Statistical Analysis" (1988): This work focuses on the hard core model, a specific type of point process where points are forbidden to be too close to each other.
* "Spatial Patterns and Stochastic Geometry" (1996): This book, co-authored with Jesper Møller, provides a comprehensive overview of stochastic geometry and its applications in fields like forestry, geology, and astrophysics.
Beyond these specific works, Matern also published numerous articles in scientific journals, exploring various aspects of stochastic geometry and its applications.
He was a pioneer in the field, and his work continues to be influential in many areas of research and practice.
