Web30 de jan. de 2024 · A Combinatorial Problem from Group Theory. Eugene Curtin, Suho Oh. Keller proposed a combinatorial conjecture on construction of an n-by-infinite matrix, which comes from showing the existence of many orbits of different sizes in certain linear group actions. He proved it for the case n=4, and we show that conjecture is true in the … WebA public-key cryptosystem inspired in part by the Wagner-Magyarik idea, but the idea is vague, and it is dicult to find a secure realization of this idea. We analyze and critique the public-key cryptosystem, based on combinatorial group theory, that was proposed by Wagner and Magyarik in 1984. This idea is actually not based on the word problem but …
