Beals-cordes-type Characterizations of Pseudodifferential Operators
We show that, if U is the representation of SOe(n+1, 1) on L2(Sn) given by (2.11), and P is a bounded operator on L2(Sn), then P belongs to OPS0 1,0(S n) if and only if P (g) = U(g)PU(g)−1 is a C∞ function on SOe(n+1, 1) with values in the Banach space L(L2(Sn)). Introduction Let M be a compact C∞ manifold. Denote by OPS 1,0(M) the space of pseudodifferential operators on M , whose symbols in l...
متن کاملFixed Point Theory in Fréchet Spaces for Mönch Inward and Contractive Urysohn Type Operators
We present new fixed point theorems for inward and weakly inward Urysohn type maps. Also we discuss Mönch Kakutani and contractive type maps.
متن کاملSyntactic Characterizations of Belief Change Operators
We provide syntactic characterizations for a number of propositional model-based belief revision and update operators proposed in the literature, as well as algorithms based on these characterizations.
متن کاملSome characterizations based on double aggregation operators
Double aggregation operators are introduced and several basic properties are studied, as neutral and annihilator elements, idempotency, etc., which are illustrated by some examples. The classes of additive and comonotone additive double aggregation operators are characterized.
متن کاملControllability of Urysohn Integral Inclusions of Volterra Type
The aim of this paper is to study the controllability of a system described by an integral inclusion of Urysohn type with delay. In our approach we reduce the controllability problem of the nonlinear system into solvability problem of another integral inclusion. The solvability of this integral inclusion is subsequently established by imposing suitable standard boundedness, convexity and semico...
