The Principle of Covariance and the Hamiltonian Formulation of General Relativity
The implications of the general covariance principle for the establishment of a Hamiltonian variational formulation of classical General Relativity are addressed.

Timed Multiparty Session Types [PDF]
We propose a typing theory, based on multiparty session types, for modular verification of real-time choreographic interactions. To model real-time implementations, we introduce a simple calculus with delays and a decidable static proof system. The proof

Inextendibilty of the Maximal Global Hyperbolic Development in Electrogowdy spacetimes
The problem of determinism in General Relativity appears even if one assumes that the spacetime is globally hyperbolic, i.e. that it contains a hypersurface that is intersected by any causal curve exactly once.

Bounds on the power of proofs and advice in general physical theories [PDF]
Quantum theory presents us with the tools for computational and communication advantages over classical theory. One approach to uncovering the source of these advantages is to determine how computation and communication power vary as quantum theory is replaced by other operationally defined theories from a broad framework of such theories.

Termination Casts: A Flexible Approach to Termination with General Recursion [PDF]
This paper proposes a type-and-effect system called Teqt, which distinguishes terminating terms and total functions from possibly diverging terms and partial functions, for a lambda calculus with general recursion and equality types.

Log-concavity of characteristic polynomials and the Bergman fan of matroids [PDF]
In a recent paper, the first author proved the log-concavity of the coefficients of the characteristic polynomial of a matroid realizable over a field of characteristic 0, answering a long-standing conjecture of Read in graph theory.

A Generalization of Equational Proof Theory? [PDF]
Recently rule based languages focussed on the use of rewriting as a modeling tool which results in making specifications executable. To extend the modeling capabilities of rule based languages, we explored in a previous work the possibility of making the rule applications subject to probabilistic choices, and started to study the generalization of the ...

Isabelle/HOL/GST: A Formal Proof Environment for Generalized Set Theories
A generalized set theory (GST) is like a standard set theory but also can have non-set structured objects that can contain other structured objects including sets. This paper presents Isabelle/HOL support for GSTs, which are treated as type classes that combine features that specify kinds of mathematical objects, e.g., sets, ordinal numbers, functions,

Local newforms for the general linear groups over a non-archimedean local field
In [14], Jacquet–Piatetskii-Shapiro–Shalika defined a family of compact open subgroups of p-adic general linear groups indexed by nonnegative integers and established the theory of local newforms for irreducible generic representations. In this paper, we

G. L\"uders and W. Pauli proved the $\mathcal{CPT}$ theorem based on Lagrangian quantum field theory almost half a century ago. R. Jost gave a more general proof based on ``axiomatic'' field theory nearly as long ago.
