We present FORM 5, a major release of the symbolic-manipulation system FORM. Version 5 introduces an integrated diagram generator, based on the GRACE graph-generator, to produce Feynman diagrams directly from FORM scripts. This release also adds support for arbitrary precision floating point coefficients, together with statements for the numerical evaluation of common mathematical functions as well as multiple zeta values and Euler sums. In addition, FORM 5 provides an interface to the FLINT library, offering substantially faster polynomial arithmetic. Various further functions and commands have been added alongside these major features, as well as performance improvements for TFORM and improved compression of FORM's temporary files. Compatibility with the previous release, FORM 4.3.1, is retained except where prior behaviour contradicted the manual or was experimental.
翻译:我们发布 FORM 5,这是符号处理系统 FORM 的一个主要版本。版本 5 引入了一个基于 GRACE 图生成器的集成化图表生成器,能够直接从 FORM 脚本生成费曼图。此版本还增加了对任意精度浮点系数的支持,以及用于数值计算常见数学函数、多重 zeta 值和欧拉和的语句。此外,FORM 5 提供了与 FLINT 库的接口,实现了显著更快的多项式运算。除了这些主要特性外,还增加了各种其他函数和命令,并对 TFORM 进行了性能改进,同时优化了 FORM 临时文件的压缩。除了先前版本 FORM 4.3.1 中与手册相矛盾或处于实验阶段的行为外,本版本保持了与之前版本的兼容性。
