Differential Operators on a Cubic Cone
Consider in the space C with the coordinates x{ , x2, x3 the surface X defined by the equation x\ + x\ + x\ = 0. We prove the following theorem: T H E O R E M 1. Let D{X) be the ring of regular differential operators on X, and Da the ring of germs at the point 0 of analytic operators on X. Then 1°. the rings D(X) and Da are not Noetherian; 2°. for any natural number k the rings D{X) and Da are ...
متن کاملOn Optimality Conditions via Weak Subdifferential and Augmented Normal Cone
In this paper, we investigate relation between weak subdifferential and augmented normal cone. We define augmented normal cone via weak subdifferential and vice versa. The necessary conditions for the global maximum are also stated. We produce preliminary properties of augmented normal cones and discuss them via the distance function. Then we obtain the augmented normal cone for the indicator f...
متن کاملComputation of Graphical Derivative for a Class of Normal Cone Mappings under a Very Weak Condition
Let Γ := {x ∈ R | q(x) ∈ Θ}, where q : R → R is a twice continuously differentiable mapping, and Θ is a nonempty polyhedral convex set in R. In this paper, we first establish a formula for exactly computing the graphical derivative of the normal cone mapping NΓ : R ⇒ R, x 7→ NΓ(x), under the condition that Mq(x) := q(x) − Θ is metrically subregular at the reference point. Then, based on this fo...
متن کاملA Note on the Index of Cone Differential Operators
We prove that the index formula for b-elliptic cone differential operators given by Lesch in [6] holds verbatim for operators whose coefficients are not necessarily independent of the normal variable near the boundary. We also show that, for index purposes, the operators can always be considered on weighted Sobolev spaces.
متن کاملInertial Manifolds and the Cone Condition
The “cone condition”, used in passing in many proofs of the existence of inertial manifolds, is examined in more detail. Invariant manifolds for dissipative flows can be obtained directly using no other dynamical information. After finding a condition for the exponential attraction of trajectories to such a manifold, a cone invariance property is used to show the existence of orbits on the mani...
