Riesz* Homomorphisms on the copositive Cone

Pavankumar Raickwade, K. C. Sivakumar

The paper characterizes linear maps that preserve the cone of K‑copositive symmetric matrices by studying Riesz* homomorphisms, providing a representation theorem, and introducing…

Generalized Inverse Preservers of Hadamard Circulant Majorization

C. C. Hsu, P. R. Raickwade, K. C. Sivakumar

Let $T : M_{n} \to M_{n}$ preserve Hadamard circulant majorization. In this note, we show that this property is inherited by the three most popular generalized inverses, viz…
