Solution stationnaire du système d'équations de la radiation et de la température dans l'air
2010 Mathematics Subject Classification: 35Q79 (35J61, 86A10). We consider the integro-differential equation system which describes the intensity of the radiation and the temperature of the air in a domain of R^3. Supposing that the coefficients of absorbation and emission of radiation are small even if they depend on the position, we prove the existence of a stationary solution of the equation system in a bounded domain.
