Hom--Lie Algebras and Explicit MSS Partition Bounds for Biangular Frames
Abraham Orinda, Geoffrey Mboya, Arvince Ogendi
We study the algebraic structure of biangular Parseval frames. The two-distance property yields adjacency matrices whose span forms a three-dimensional commutativ…

A Finiteness Theorem for Quartic K3-Fibred Calabi--Yau Threefolds in Scrolls
Geoffrey Mboya
We study a restricted form of Gross's finiteness problem for algebraic minimal Calabi--Yau threefolds: those fibred by quartic K3 surfaces and realised as anticanonical hypersurfac…

CICY3 Families of Nonsingular Codimension two K3
Geoffrey Mboya
We conduct a systematic search of codimension 2 Complete Intersection Calabi--Yau threefolds (CICY3) in rank 2 toric ambient spaces and fibered by complete intersection of a quadri…
