However if " X " is a Hilbert space there is exactly one closed ideal sandwiched between the Riesz operators and those of finite rank.

His successful research projects include the resolution of the commutative Singer-Wermer conjecture and construction of a non-standard closed ideal in a certain radical Banach algebra of power series and their quotients.
3.
An " "'inharmonic partial " "'is any partial that does not match an ideal harmonic . " Inharmonicity " is a measure of the deviation of a partial from the closest ideal harmonic, typically measured in cents for each partial.
4.
Their goal, like that of the Symbolists before them, was equivalent to an escape from reality . " Yet there were important distinctions ", write Robbins, " for the Abbaye intention to create a total future a priori ruled out the Symbolist technique of creating solely from an aesthetic or a closed ideal ".
