Sheaf Of regular functions
Rani Kumari, Umesh Kumar V Dubey
In this paper, we proved that for an affine variety V in A^n; O_V is a sheaf of regular functions and the ringed space pair (V;O_V ) is a locally ringed space.
Factorizations of Kernels and Reproducing Kernel Hilbert Spaces
Rani Kumari, Jaydeb Sarkar, Srijan Sarkar +1
The paper discusses a series of results concerning reproducing kernel Hilbert spaces, related to the factorization of their kernels. In particular, it is proved that for a large cl…
Some generalisations of the inequalities for positive linear maps
R. Sharma, P. Devi, R. kumari
We obtain generalisations of some inequalities for positive unital linear maps on matrix algebra. This also provides several positive semidefinite matrices and we get some old and…
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…
