http://ift.tt/eA8V8J For a finite countably decomposable von Neumann algebra L we study the structures of the space consisting of all yon Neumann subalgebras of L. Especially we study the relation M ~N which was previously studied by Murray and von. Neumann [1 l] and McDuff [9]. Much of the techniques used are ... from Algebra

http://ift.tt/eA8V8J Welding should be considered an alternative to taking Algebra 2, he said. “You need Algebra 2 to be able to weld,” Hadden said. “We're not trying to lower the standards, we're trying to keep the standards high but give some alternatives out there that could allow people to work with their hands and still ... from Algebra

http://ift.tt/eA8V8J High school students often balk at taking algebra . “When will I ever need to use algebra later in life?” is a common refrain. But an algebra class may have saved students' lives at Marjory Stoneman Douglas High on Wednesday — or its fast-thinking teacher, Shanthi Viswanathan, to be exact. When the ... from Algebra
