Applications and Methods for Recognition of (Anti)-Symmetric Functions

چکیده
One of the important advantages held by computer algebra systems (CAS) over purely-numerical computational frameworks is that the CAS can provide a higher-level “symbolic” viewpoint for problem solving. Sometimes this can convert apparently impossible problems to trivial ones. Sometimes the symbolic perspective can provide information about questions which cannot be directly answered, or questions which might be hard to pose. For example, we might be able to analyze the asymptotic behavior of a solution to a differential equation even though we cannot solve the equation. One route to implicitly solving problems is the use of symmetry arguments. We suggest how, through symmetry, one can solve a large class of definite integration problems, including ones that are not currently solved by computer algebra systems. One case of symmetry provides for recognition of periodicity, and this solves additional problems, since removal of periodic components can be important in integration and in asymptotic expansions.

ON THE FUNCTION OF BLOCK ANTI DIAGONAL MATRICES AND ITS APPLICATION
The matrix functions appear in several applications in engineering and sciences. The computation of these functions almost involved complicated theory. Thus, improving the concept theoretically seems unavoidable to obtain some new relations and algorithms for evaluating these functions. The aim of this paper is proposing some new reciprocal for the function of block anti diagonal matrices. More...
متن کاملThe exponential functions of central-symmetric $X$-form matrices
It is well known that the matrix exponential function has practical applications in engineering and applied sciences. In this paper, we present some new explicit identities to the exponential functions of a special class of matrices that are known as central-symmetric $X$-form. For instance, $e^{mathbf{A}t}$, $t^{mathbf{A}}$ and $a^{mathbf{A}t}$ will be evaluated by the new formulas in this par...

In this paper, we show that a pointwise symmetric pre-isotonic preclosure function is uniquely determined the pairs of sets it separates. We then show that when the preclosure function of the domain is pre-isotonic and the pre-closure function of the codomain is pre-isotonic and pointwise-pre-symmetric, functions which separate only those pairs of sets which are already separated are precontinu...

متن کاملPolarization constant $mathcal{K}(n,X)=1$ for entire functions of exponential type
In this paper we will prove that if $L$ is a continuous symmetric n-linear form on a Hilbert space and $widehat{L}$ is the associated continuous n-homogeneous polynomial, then $||L||=||widehat{L}||$. For the proof we are using a classical generalized inequality due to S. Bernstein for entire functions of exponential type. Furthermore we study the case that if X is a Banach space then we have t...
