By Petre P. Teodorescu,Nicolae-A.P. Nicorovici

The proposal of crew is prime in our days, not just in arithmetic, but in addition in classical mechanics, electromagnetism, conception of relativity, quantum mechanics, concept of effortless debris, and so forth. This proposal has constructed in the course of a century and this improvement is hooked up with the names of significant mathematicians as E. Galois, A. L. Cauchy, C. F. Gauss, W. R. Hamilton, C. Jordan, S. Lie, E. Cartan, H. Weyl, E. Wigner, and of many others. In arithmetic, as in different sciences, the straightforward and fertile rules make their method with hassle and slowly; although, this lengthy historical past might were of a minor curiosity, had the inspiration of staff remained attached in simple terms with really limited domain names of arithmetic, these within which it happened before everything. yet at the present, teams have invaded just about all mathematical disciplines, mechanics, the biggest a part of physics, of chemistry, and so on. We may possibly say, with out exaggeration, that this is often crucial concept that happened in arithmetic because the invention of infinitesimal calculus; certainly, the proposal of staff expresses, in an actual and operational shape, the obscure and common principles of regularity and symmetry. The suggestion of workforce ended in a profound realizing of the nature of the legislation which govern common phenomena, allowing to formulate new legislation, correcting sure insufficient formulations and delivering unitary and non­ contradictory formulations for the investigated phenomena.
