Arthur Cayley.
English mathematician Arthur Cayley (August 16, 1821 – January 26, 1895), one of the greatest and most prolific mathematicians, helped found the British school of pure mathematics. He was one of the first to realize how many different areas of mathematics could be drawn together by the theory of groups. Together with James Joseph Sylvester, Cayley established the theory of algebraic invariants,...
متن کاملArthur Cayley and the First Paper on Group Theory
Arthur Cayleys 1854 paper On the theory of groups, as depending on the symbolic equation n = 1 inaugurated the abstract idea of a group [2]. I have used this very understandable paper several times for reading, discussion, and homework in teaching introductory abstract algebra, where students are rst introduced to group theory.

It is, however, not clear how to choose the generators to produce special graphs. We know many topologies and their generators, but many more may be constructed in the future, having better properties (in terms of diameter, nodal degree and connectivity) than for instance the hypercube. I will present several graphs which connect rings using the generator g 1 and some additional generators.

Operation for removal of clot is not an accepted procedure apart from valvotomy. The statement that valvotomy is indicated "provided the valve is suitable for it...
