Generalized probabilistic theories without the no-restriction hypothesis

- Peter Janotta, Raymond Lal
- Mathematics
- 11 February 2013

The framework of generalized probabilistic theories (GPTs) is a popular approach for studying the physical foundations of quantum theory. The standard framework assumes the no-restriction hypothesis,… Expand

Causal Categories: Relativistically Interacting Processes

- B. Coecke, Raymond Lal
- Mathematics
- 29 July 2011

A symmetric monoidal category naturally arises as the mathematical structure that organizes physical systems, processes, and composition thereof, both sequentially and in parallel. This structure… Expand

On modifications of Reichenbachʼs principle of common cause in light of Bellʼs theorem

- E. Cavalcanti, Raymond Lal
- Philosophy
- 27 November 2013

Bellʼs 1964 theorem causes a severe problem for the notion that correlations require explanation, encapsulated in Reichenbachʼs principle of common cause. Despite being a hallmark of scientific… Expand

Categorical Generalization and Physical Structuralism

- Raymond Lal, Nicholas J. Teh
- PhilosophyThe British Journal for the Philosophy of Science
- 11 April 2014

Category theory has become central to certain aspects of theoretical physics. Bain ([2013]) has recently argued that this has significance for ontic structural realism. We argue against this claim.… Expand

Causal structure in categorical quantum mechanics

- Raymond Lal
- Physics
- 2012

Categorical quantum mechanics is a way of formalising the structural features of quantum theory using category theory. It uses compound systems as the primitive notion, which is formalised by using… Expand
