"Non-thermal, leptonic radiation processes have been extensively studied for the interpretation\r\nof the observed radiation from jets of Active Galactic Nuclei (AGN).\r\nThis work addresses the synchrotron and Inverse Compton scattering (ICS) mechanisms,\r\nand investigates the potential of a self-consistent, time-dependent approach\r\nto currently unsolved problems. Furthermore, it examines how deviations from standard,\r\none-zone models can modify the radiated spectrum. A detailed analysis of the\r\nshape of the ICS spectrum is also performed.\r\nIn the first part a possible interpretation of the hard γ-ray blazar spectra in the\r\nframework of leptonic models is investigated. It is demonstrated that hard γ-ray\r\nspectra can be generated and maintained in the presence of energy losses, under the\r\nbasic assumption of a narrow electron energy distribution (EED). Broader spectra\r\ncan also be modeled if multiple zones contribute to the emission. In such a scheme,\r\nhard flaring events, like the one in Mkn 501 in 2009, can be successfully interpreted\r\nwithin a \"leading blob\" scenario, when one or few zones of emission become dominant.\r\nIn the second part the shape of the Compton spectrum close to the maximum cutoff is investigated. Analytical approximations for the spectral shape in the cutoff\r\nregion are derived for various soft photon fields, providing a direct link between the\r\nparent EED and the upscattered spectrum. Additionally, a generalization of the\r\nbeaming pattern for various processes is derived, which accounts for non-stationary,\r\nanisotropic and non-homogeneous EEDs. It is shown that anisotropic EEDs may\r\nlead to radiated spectra substantially different from the isotropic case. Finally, a\r\nself-consistent, non-homogeneous model describing the synchrotron emission from\r\nstratified jets is developed. It is found that transverse jet stratification leads to\r\ncharacteristic features in the emitted spectrum different to expectations in homogeneous\r\nmodels."^^ . "2003-12-12" . . . .
