The Gorenstein locus of minuscule Schubert varieties

In this article, we explicitly describe the Gorenstein locus of all minuscule Schubert varieties. This proves a special case of the conjecture of A. Woo and A. Yong [Alexander Woo, Alexander Yong, Governing singularities of Schubert varieties, J. Algebra 320 (2) (2008) 495–520] regarding the Gorenstein locus of Schubert varieties.
