A Newton-type method and its application (2006)

V. Antony Vijesh, P. V. Subrahmanyam

We prove an existence and uniqueness theorem for solving the operator equation F(x)+G(x)=0, where F is a continuous and Gâteaux differentiable operator and the operator G satisfies Lipschitz...

Existence of solutions for equations involving iterated functional series (2005)

V. Murugan, P. V. Subrahmanyam

Theorems on the existence and uniqueness of differentiable solutions for a class of iterated functional series equations are obtained. These extend earlier results due to Zhang.

A note on the spectra of epsilon Aurigae (1993)

Subrahmanyam, P. V, Raghavender Rao, C, Sreedhar Rao, S

Spectroscopic observations of the long period variable epsilon Aurigae were made during its 1982-84 eclipse. It is found that the Ca II H and K lines show variation in their equivalent widths. The...

Correction for the observed intensity distribution in solar corona (1984)

Abhyankar, K. D, Subrahmanyam, P. V

An estimation of the correction for the broadening of the intensity profile of the solar corona caused by atmospheric turbulence, scattering in the photographic emulsion, focusing errors etc, is made...
