This paper presents EXTERIOR, a dual-VM architecture based external shell that can be used for trusted, timely out-of-VM management of guest-OS such as introspection, configuration, and recovery. Inspired by recent advances in virtual machine introspection (VMI), EXTERIOR leverages an isolated, secure virtual machine (SVM) to introspect the kernel ...

On the Tubes of Exterior Algebras
Algebra Colloquium, 2006In this paper, we study the Koszul modules of complexity 1 of an exterior algebra of a vector space V over an algebraically closed field. We prove that there are ℙ (V)-orthogonal families of such modules, each of which consists of Koszul modules filtered by the cyclic ones corresponding to the same point in ℙ (V). We also prove that they are invariant

Exteriorized colonic anastomosis
International Journal of Colorectal Disease, 1991The risk of anastomotic failure in the unprepared colon is generally high. Therefore, Hartmann's operation is frequently employed in emergencies. We present an alternative technique, the exteriorized anastomosis described until now only for cases of perforation. Exteriorized anastomosis was performed in 14 patients.

A note on the exterior centralizer
Archiv der Mathematik, 2009If \(G\) is a group, the exterior square of \(G\) is the group \(G\wedge G\) generated by the symbols \(g\wedge h\) and subject to the relations \(g\wedge g=1\), \(g_1g_2\wedge h=(g_1g_2g_1^{-1}\wedge g_1hg_1^{-1})(g_1\wedge h)\) and \(g\wedge h_1h_2=(g\wedge h_1)(h_1gh_1^{-1}\wedge h_1h_2h_1^{-1})\) for all \(g,g_1,g_2,h,h_1,h_2\in G\).

A Homomorphism in Exterior Algebra
Canadian Journal of Mathematics, 1964In the following, V is a vector space over an arbitrary field F, dimFV = n. Let {e1, . . . , en} be a basis for V, and {f1, . . . , fn} be the dual basis for and , then the operators *(u) and i(g) (exterior and inner multiplication by u and g respectively) set up an equivalence between the ideal = range of ∊(u) and the sub-algebra = range of i(g ...

On the exterior structure of graphs
Journal of Mathematical Physics, 2004After a detailed ab initio description of the exterior structure of graphs as handled by Connes and Kreimer in their work on renormalization (illustrated by the example of the φ3 model in six dimensions) we spell out in detail their study of the Lie algebra of infinitesimal characters and of the group of characters of the Hopf algebra of Feynman graphs.

A skew-symmetric map of type (p, q) from E*, E into a vector space H is a (p + q)-linear mapping $$\psi :\underbrace {E* \times \ldots \times E*}_p \times \underbrace {E \times \ldots \times E}_q \to H$$ which satisfies $$\psi (x_{\sigma (1)}^*, \ldots ,x_{\sigma (p)}^*;{x_{\tau (q)}}) = {\varepsilon _\sigma }{\varepsilon _\tau }\psi (x_1^*,

Exterior Topology and Revision Spaces
Journal of Logic and Computation, 1995Summary: A mathematical model of knowledge base revision attempts to faithfully capture an intuitive notion of `closest' new information relative to some given background information. An attempt to topologically characterize this notion of closest information leads naturally to an approach using non-monotonic exterior operators in contrast to standard ...
