英文摘要:
We investigate the existence of affine realizations for term structure models driven by L\\\'evy processes. It turns out that we obtain more severe restrictions on the volatility than in the classical diffusion case without jumps. As special cases, we study constant direction volatilities and the existence of short rate realizations.

中文摘要:
我们研究了由列维过程驱动的项结构模型的仿射实现的存在性。结果表明,与没有跳跃的经典扩散情况相比,我们对波动率得到了更严格的限制。作为特例,我们研究了恒定方向波动和短期利率变现的存在性。
