Schur multipliers and second quandle homology

Rhea Palak Bakshi , Dionne Ibarra , Sujoy Mukherjee , Takefumi Nosaka , Józef Henryk Przytycki


We define a map from second quandle homology to the Schur multiplier and examine its properties. Furthermore, we express the second homology of Alexander quandles in terms of exterior algebras. Additionally, we present a self-contained proof of its structure and provide some computational examples.
