Tau Functions Associated to Pseudodifferential Operators of Several Variables
Pseudodifferential operators of several variables are formal Laurent series in the formal inverses of ∂1, . . . , ∂n with ∂i = d/dxi for 1 ≤ i ≤ n. As in the single variable case, Lax equations can be constructed using such pseudodifferential operators, whose solutions can be provided by Baker functions. We extend the usual notion of tau functions to the case of pseudodifferential operators of ...
متن کاملCasimir Operators on Pseudodifferential Operators of Several Variables
We study the actions of the Lie algebra nsl(2,C) of SL(2,C) and the associated Casimir operator on the space of pseudodifferential operators of n variables. We describe the effect of the Casimir operator on a pseudodifferential operator in connection with the symbol map and construct an nsl(2,C)-invariant lifting of the symbol map.
متن کاملSubmajorization inequalities associated with $tau$-measurable operators
The aim of this note is to study the submajorization inequalities for $tau$-measurable operators in a semi-finite von Neumann algebra on a Hilbert space with a normal faithful semi-finite trace $tau$. The submajorization inequalities generalize some results due to Zhang, Furuichi and Lin, etc..
متن کاملApproximately generalized additive functions in several variables
The goal of this paper is to investigate the solutionand stability in random normed spaces, in non--Archimedean spacesand also in $p$--Banach spaces and finally the stability using thealternative fixed point of generalized additive functions inseveral variables.
متن کاملClasses of admissible functions associated with certain integral operators applied to meromorphic functions
In the present paper, by making use of the differential subordination and superordination results of Miller and Mocanu, certain classes of admissible functions are determined so that subordination as well as superordination implications of functions associated with an integral operator hold. Additionally, differential sandwich-type result is obtained.
