Reasoning about permissions and obligations sometimes requires to distinguish more than one level of permission: certain actions are preferable to others, or one has more confiden...
We present an extension to classical separation logic which allows reasoning about virtual memory. Our logic is formalised in the Isabelle/HOL theorem prover in a manner allowing ...
: We define a regularity axiom for lattice-valued convergence spaces where the lattice is a complete Heyting algebra. To this end, we generalize the characterization of regularity ...
The adaption of combinatorial duality to infinite graphs has been hampered by the fact that while cuts (or cocycles) can be infinite, cycles are finite. We show that these obstruc...
The objective of this note is to prove, under certain technical conditions, that the top-Lyapunov exponent of a strictly stationary random sequence of block-triangular matrices is...
