Introduction {à} l'oeuvre de S. Kichenassamy en Physique Th{é}orique
摘要：
S. Kichenassamy（1926-2015）在理论和数学物理涵盖了相对论物理学的光谱：从相对论的两个理论的假设基础的澄清，应用到测量适当的时间，图像形成，碰撞理论，动力学理论和辐射转移，或脉冲星电动力学，仅举几例。经过简短的传记评论，我们表明，以下的论点首先制定于1963年，并在一系列的文件，即物理解释的广义相对论需要取代强等效原则的C-等效原则。通过给予观察者一个数学的地位，他的洞察力产生了关于实际观察者可以进行的测量的新结果，无论是在狭义相对论还是在广义相对论中。应用概述。他对印度学的贡献将在其他地方讨论。
英文摘要：
The work of S. Kichenassamy (1926-2015) in Theoretical and Mathematical Physics covers the spectrum of Relativistic Physics: from the clarification of the postulational basis of the two theories of Relativity, to applications to the measurement of proper time, image formation, collision theory, kinetic theory and radiative transfer, or pulsar electrodynamics, to name a few. After brief biographic remarks,we show, by following an argument first formulated in 1963, and developed in a series of papers, that the physical interpretation of General Relativity requires the replacement of the strong equivalence principle by the C-equivalence principle. By giving a mathematical status to the observer, his insight yields new results regarding measurements actual observers can make, both in Special and in General Relativity. Applications are outlined. His contributions to Indology will be discussed elsewhere.
