Large sets in $\mathbb{N}$ have strong combinatorial structures. For example, it is known that central sets in $\mathbb{N}$ contain arbitrarily long arithmetic progressions. It also contains solutions to all partition regular systems of homogeneous linear equations.
My question: Are there any real-world research applications of all this methodology? Can anyone suggest me any book or research articles where I will get the real world application of Large sets, such as syndetic sets, central sets, etc?
Thank you in advance. Any help will be appreciated.
