This paper considers the possibility that abstract thinking and advanced synthesis skills might encourage extraterrestrial civilizations to accept communication with mankind on Earth. For this purpose, a notation not relying upon the use of alphabet and numbers is proposed, in order to denote just some basic geometric structures of current physical theories: vector fields, $1$-form fields, and tensor fields of arbitrary order. An advanced civilization might appreciate the way here proposed to achieve a concise description of electromagnetism and general relativity, and hence it might accept the challenge of responding to our signals. The abstract symbols introduced in this paper to describe the basic structures of physical theories are encoded into black and white bitmap images that can be easily converted into short bit sequences and modulated on a carrier wave for radio transmission.

本文考虑了抽象思维和高级综合技能可能鼓励地外文明接受与地球人类交流的可能性。为此，提出了一种不依赖于字母和数字使用的符号，以便仅表示当前物理理论的一些基本几何结构：矢量场，$1$-形式字段和任意顺序的张量字段。一个先进的文明可能会欣赏这里提出的实现电磁学和广义相对论的简洁描述的方法，因此它可能会接受响应我们的信号的挑战。本文引入的描述物理理论基本结构的抽象符号被编码为黑白位图图像，这些图像可以很容易地转换为短位序列并调制在载波上进行无线电传输。
