Abstract |
|
|
| We give an existence theorem for some quadratic functional equations which includes many key integral and functional
equations that arise in nonlinear analysis and its applications. In particular, we extend the class of characteristic functions appearing
in Chandrasekhar’s classical integral equation from astrophysics and retain existence of its solutions. Also, some counter examples are
considered. |
