Inner Model Operators in L(R)

Invariant subspaces of nilpotent operators and LR-sequences

It is well-known that an operator in a finite-dimensional vector space is uniquely determined up to a similarity by its Jordan model. Given an operator T , two invariant subspaces M and N of T are said to be similar if there exists an invertible operator X such that XT = TX and XM = N . Clearly this is an equivalence relation in the lattice of invariant subspaces of T . Our paper was originally...

Generating Macro-Operators by Exploiting Inner Entanglements

In Automated Planning, learning and exploiting additional knowledge within a domain model, in order to improve plan generation speed-up and increase the scope of problems solved, has attracted much research. Reformulation techniques such as those based on macro-operators or entanglements are very promising because they are to some extent domain model and planning engine independent. This paper ...

Numerical Range of Two Operators in Semi-Inner Product Spaces

and Applied Analysis 3 was studied by Verma 14 . He defined the numerical range VL T of a nonlinear operator T , as VL T : { Tx, x [ Tx − Ty, x − y ‖x‖ ∥x − y∥2 : x, y ∈ D T , x / y } . 1.3 He used this concept to solve the operator equation Tx−λx y, where T is a nonlinear operator. This paper is concerned with the numerical range in a Banach space. Nanda 15 studied the numerical range for two ...
