unimodular property
21Spectrum of a C*-algebra — The spectrum of a C* algebra or dual of a C* algebra A, denoted Â, is the set of unitary equivalence classes of irreducible * representations of A. A * representation π of A on a Hilbert space H is irreducible if, and only if, there is no closed… …
22Eisenstein series — This article describes holomorphic Eisenstein series; for the non holomorphic case see real analytic Eisenstein series In mathematics, Eisenstein series, named after German mathematician Gotthold Eisenstein, are particular modular forms with… …
23Regular number — The numbers that evenly divide the powers of 60 arise in several areas of mathematics and its applications, and have different names coming from these different areas of study. As an example, 602 = 3600 = 48 times; 75, so both 48 and 75 are… …
24Linear programming relaxation — In mathematics, the linear programming relaxation of a 0 1 integer program is the problem that arises by replacing the constraint that each variable must be 0 or 1 by a weaker constraint, that each variable belong to the interval [0,1] .That is,… …
25Gerard Murphy (professor) — Gerard J. Murphy MRIA was a prolific Irish mathematician.His textbooks are internationally acclaimed, and translated into different languages. He died from cancer in October 2006, at the age of 57. Research Gerard s research was in functional… …
26Pascal matrix — In mathematics, particularly matrix theory and combinatorics, the Pascal matrix is an infinite matrix containing the binomial coefficients as its elements. There are 3 ways this can be achieved either as an upper triangular matrix, a lower… …
27Tempered representation — In mathematics, a tempered representation of a linear semisimple Lie group is a representation that has a basis whose matrix coefficients lie in the L p space : L 2+ epsilon;( G ) for any epsilon; gt; 0. FormulationThis condition, as just given,… …
28Boundedly generated group — In mathematics, a group is called boundedly generated if it can be expressed as a finite product of cyclic subgroups. The property of bounded generation is also closely related with the congruence subgroup problem (see harvnb|Lubotzky|Segal|2003) …
