Journal Archive

Browse published research by volume, issue and publication date.

The archive preserves access to previously published journal content. Readers can use it to locate articles by volume, issue, year, title or author and to consult the official version of record.

Scholarly Record

Where a correction, retraction or other post-publication notice becomes necessary, the relevant article record should remain identifiable and linked to the notice. This approach protects transparency and the continuity of scholarly communication.

Certified Conjugacy Learning in Small-Cancellation Groups

Michael Nsikan John

The conjugacy decision problem is fundamental in combinatorial group theory and has applications in algebraic cryptography. Previous machine-learning studies demonstrated that conjugacy can be classified in selected non-free groups, but a statistical prediction is not an algebraic proof. This paper…

Cumulative-Exposure Thresholds in Post-Quantum Migration Risk: An Occupation-Time Model with Exact Passage Laws

Tombotamunoa W. J. Lawson

A Markov model that allows a vulnerable cryptographic deployment to return to a safe state can inadvertently erase risk accumulated before remediation. We formulate a cumulative-exposure threshold model for post-quantum migration analysis. A two-state continuous-time chain alternates between protec…
