Do backrun auctions protect traders?
Andrew W. Macpherson
We study a new "laminated" queueing model for orders on batched trading venues such as decentralised exchanges. The model aims to capture and generalise transaction queueing infras…
Adversarial blockchain queues and trading on a CFMM
Andrew W. Macpherson
We describe a plausible probabilistic model for a blockchain queueing environment in which rational, profit-maximising schedulers impose adversarial disciplines on incoming message…
Adjoining colimits
Andrew W. Macpherson
This paper develops a theory of colimit sketches "with constructions" in higher category theory, formalising the input to the ubiquitous procedure of adjoining specified "construct…
Fibrations and Koszul duality in locally Cartesian localisations
Andrew W. Macpherson
I show that any locally Cartesian left localisation of a presentable infinity-category admits a right proper model structure in which all morphisms are cofibrations, and obtain a K…
An alternative to hypercovers
Andrew W. Macpherson
I introduce a class of diagrams in a Grothendieck site called "atlases" which can be used to study hyperdescent, and show that hypersheaves take atlases to limits using an indexed…
A bivariant Yoneda lemma and -categories of correspondences
Andrew W. Macpherson
Everyone knows that if you have a bivariant homology theory satisfying a base change formula, you get an representation of a category of correspondences. For theories in which the…
