查询词典 operator algebra

Whenever calculus is brought in, or higher algebra, you could take it as a warning that the operator was trying to substitute theory for eperience, and usually also to give to speculation the deceptive guise of investment.

一旦引入了微积分或者高等代数，你可以把这看作是一个警告，这意味着使用数学者是在用理论代替经验。通常这给了投机欺骗性的伪装，变得好像是投资一样。

" "Mathematics is ordinarily considered as producing precise and dependable results; but in the stock market the more elaborate and abstruse the mathematics the more uncertain and speculative are the conclusions we draw there from … Whenever calculus is brought in, or higher algebra, you could take it as a warning that the operator was trying to substitute theory for experience, and usually also to give to speculation the deceptive guise of investment.

As an extension, we also obtain some sufficient and necessary conditions under which M_c is left Fredholm and left Weyl for some left invertible operator C, respectively.In chapter 2, the sufficient and necessary condition under which the difference of two idempotent operators on infinite dimensional Hilbert spaces is Fredholm (in-vertible) is discussed. In addition, some equivalent conditions under which products and differences of projections in a C~*-algebra are Moore-Penrose invert-ible are obtained.
