Cut-norms and spectra of matrices
One of the aims of this paper is to solve an open problem of Lovász about relations between graph spectra and cut-distance. The paper starts with several inequalities between two versions of the cut-norm and the two largest singular values of arbitrary complex matrices, extending, in particular, the well-known graph-theoretical Expander Mixing Lemma and giving a hitherto unknown converse of it....
متن کاملOn the Expectation of Operator Norms of Random Matrices
We prove estimates for the expected value of operator norms of Gaussian random matrices with independent (but not necessarily identically distributed) and centered entries, acting as operators from `p∗ to ` m q , 1 ≤ p∗ ≤ 2 ≤ q <∞.
متن کاملOperator norms of words formed from positive-definite matrices
Let α1, α2, . . . , αn, β1, β2, . . . , βn be strictly positive reals with α1 +α2 + · · ·+αn = β1 + β2 + · · ·+ βn = s. In this paper, the inequality |||Aα1Bβ1Aα2 · · ·AαnBβn ||| ≤ |||AB|||s when A and B are positive-definite matrices is studied. Related questions are also studied.

امروزه، این که زبان انگلیسی سریع ترین و گسترده ترین زبان مورد استفاده در سراسر جهان است به عنوان یک واقعیت پذیرفته شده است. استفاده مشترک از زبان انگلیسی به عنوان یک زبان بین المللی مستلزم هنجارها و مدل های یادگیری و تدریس زبان است. زبان شناسان توجه ویژه ای به مفهوم "زبان مادری" به عنوان تنها منبع درست و قابل اعتماد از داده های زبان می داده اند.با این حال، این اصطلاح به اندازه کافی روشن به نظر ...
15 صفحه اولOn the spectra of some matrices derived from two quadratic matrices
begin{abstract} The relations between the spectrum of the matrix $Q+R$ and the spectra of the matrices $(gamma + delta)Q+(alpha + beta)R-QR-RQ$, $QR-RQ$, $alpha beta R-QRQ$, $alpha RQR-(QR)^{2}$, and $beta R-QR$ have been given on condition that the matrix $Q+R$ is diagonalizable, where $Q$, $R$ are ${alpha, beta}$-quadratic matrix and ${gamma, delta}$-quadratic matrix, respectively, of ord...
