چکیده
Abstract We give necessary and sufficient conditions on an m -isometry to have invertible -isometrical extension. As particular cases, we a useful characterization for general unilateral weighted shift $$\ell $$ ℓ -Jordan isometries. In particular, every isometry operator has $$(2\ell -1)$$ ( 2 - 1 )

Locally Invertible m-Dimensional Convolutional Codes
A new approach for decoding multidimensional (mD) nonsystematic convolutional codes is described. The possibility of coding at different rates along the dimensions of the sequence space is explored and the notion of ordering of information and encoded sequences based on coding rate is explained. Using this technique, a class of fast-decodeable, locally invertible m-D convolutional codes based o...
متن کاملExtension to an invertible matrix in convolution
Let M+ denote the Banach algebra of all complex Borel measures with support contained in [0, +∞), with the usual addition and scalar multiplication, and with convolution ∗, and the norm being the total variation of μ. We show that the maximal ideal space X(M+) of M+, equipped with the Gelfand topology, is contractible as a topological space. In particular, it follows that every left invertible ...

Transient Solution of an M/M/1 Variant Working Vacation Queue with Balking
This paper presents the transient solution of a variant working vacation queue with balking. Customers arrive according to a Poisson process and decide to join the queue with probability $b$ or balk with $bar{b} = 1-b$. As soon as the system becomes empty, the server takes working vacation. The service times during regular busy period and working vacation period, and vacation times are assumed ...

Abstract. Let Mn;m be the set of n-by-m matrices with entries inthe field of real numbers. A matrix R in Mn = Mn;n is a generalizedrow substochastic matrix (g-row substochastic, for short) if Re e, where e = (1; 1; : : : ; 1)t. For X; Y 2 Mn;m, X is said to besgut-majorized by Y (denoted by X sgut Y ) if there exists ann-by-n upper triangular g-row substochastic matrix R such thatX = RY . This ...
