in this article, we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators. considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...

Mundja is a MAC generation algorithm that has been designed for use together with a stream cipher. Mundja accumulates the message onto two independent registers: the first is a Cyclic Redundancy Checksum (CRC) that uses linear feedback; the second is a strengthened version of the SHA-256 register [5] that uses nonlinear feedback. Mundja is fast (asymptotically about 4 times the speed of HMAC-SH...
In this paper we prove a modification of Hofmann-Mislove theorem for a topological structure similar to the minusspaces of de Groot, in which the empty set “need not be open”. This will extend, in a slightly relaxed form, the validity of the classical Hofmann-Mislove theorem also to some of those spaces, whose underlying topology need not be (quasi-) sober. Date: 11. 2. 2004. Last revision: 14....
Sober and Wilson have propose a cluster of arguments for the conclusion that ‘‘natural selection is unlikely to have given us purely egoistic motives’’ and thus that psychological altruism is true. I maintain that none of these arguments is convincing. However, the most powerful of their arguments raises deep issues about what egoists and altruists are claiming and about the assumptions they ma...

let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
We present Nonstandard Analysis by three axioms: the Extension, Transfer and Saturation Principles in the framework of the superstructure of a given innnite set. We also present several applications of this axiomatic approach to point-set topology. Some of the topological topics such as the Hewitt realcompactiication and the nonstandard characterization of the sober spaces seem to be new in the...
