Bounds on Spreads of Matrices related to Fourth Central Moment. II
R. Sharma, R. Kumar, R. Saini +1
We derive some inequalities involving first four central moments of discrete and continuous distributions. Bounds for the eigenvalues and spread of a matrix are obtained when all i…

Positive Linear Maps and Perturbation bounds of Matrices
R. Sharma, R. Kumari
We show how positive unital linear maps can be used to obtain lower bounds for the maximum distance between the eigenvalues of two normal matrices. Some related bounds for the spre…
