A rigorous guide at the crossroads of topology and choice theory, showing how connected spaces can support robust representations of preferences without separability.

This book investigates how the structure of preferences can be understood through topological ideas. It extends classic results by showing that key representations can exist under connectivity alone, relaxing older assumptions like arcwise connectedness and separability.

Explanations of semiclosed and closed preorders and how they influence representability.
Extensions of Gorman’s structure results to broader spaces, without requiring separability.
Connections to Debreu’s representation theorems and practical methods for utility construction.
A clear path from abstract theory to applications in the study of preferences and decision making.

Ideal for readers of economic theory, functional equations, and decision science who want a deeper, topology‑driven view of how preferences can be represented and analyzed.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
