NONSTANDARD LORENTZ SPACE FORMS
lorentz Space form
2015/9/29
In their recent paper [8], Kulharni and Raymond show that a closed
3-manifold which admits a complete Lorentz metric of constant curvature 1
(henceforth called a complete Lorentz structure) must be ...
THE FUNDAMENTAL GROUP OF A COMPACT FLAT LORENTZ SPACE FORM IS VIRTUALLY POLYCYCLIC
lorentz Multi-loop spatial form
2015/9/29
A flat Lorentz space form is a geodesically complete Lorentzian manifold of
zero curvature. It is well known (see Auslander & Markus [3]) that such a space
M may be represented as a quotient Rw
/Γ,...
A Desingularization of the Main Component of the Moduli Space of Genus-One Stable Maps into P n
Genus-One Stable Maps Moduli
2015/7/14
We construct a natural smooth compacti cation of the space of smooth genus-one curves with
k distinct points in a projective space. It can be viewed as an analogue of a well-known smooth
compacti ca...
A DESCRIPTION OF THE OUTER AUTOMORPHISM OF S6, AND THE INVARIANTS OF SIX POINTS IN PROJECTIVE SPACE
PROJECTIVE SPACE OUTER AUTOMORPHISM
2015/7/14
The latter two descriptions do
not distinguish any of the six points. Of course, these descriptions are equivalent to the
traditional one (x1.4) there is after all only one nontrivial outer automor...
Hypersurfaces in non-flat Lorentzian space forms satisfying $L_k\psi=A\psi+b$
linearized operator Lk isoparametric hypersurface k-maximal hypersurface
2011/1/21
We study hypersurfaces either in the De Sitter space Sn+1 1 ⊂ Rn+2 1 or in the anti De
Sitter space Hn+1 1 ⊂ Rn+2 2 whose position vector satisfies the condition Lk = A + b,
Multiple G-Itô integral in the G-expectation space
Sublinear expectation G-Brownian motion G-Itˆ o integral
2011/1/17
In this paper, motivated by mathematic finance we introduce the multiple G-Itˆo integral in the G-expectation space, then investigate how to calculate. We get the the relationship between Hermite...
A $c_0$ saturated Banach space with tight structure
c0 saturated Banach spaces space of operators saturated norms hereditarily
2011/1/21
It is shown that variants of the HI methods could yield objects closely connected to the classical Banach spaces. Thus we present a new c0 saturated space, denoted as X0,with rather tight structure.
Periodic windows distribution resulting from homoclinic bifurcations in the two-parameter space
Homoclinic systems Periodic windows Bifurcation
2010/12/28
Periodic solution parameters, in chaotic dynamical systems, form periodic windows with characteristic distribution in two-parameter spaces. Recently, general properties of this organization have been ...
Orbit determination of space objects based on sparse optical data
orbit determination space debris
2011/3/4
While building up a catalog of Earth orbiting objects, if the available optical observations
are sparse, not deliberate follow ups of specific objects, no orbit determination is possible
without pre...
Jordanian double extensions of a quadratic vector space and symmetric Novikov algebras
Jordanian double extension 2-step nilpotent pseudo-Euclidean Jordan algebras
2011/2/28
First, we study pseudo-Euclidean Jordan algebras obtained as double extensions of a quadratic vector space by a one-dimensional algebra. We give an isomorphic characterization of 2-step nilpotent pseu...
Space functions of groups
Space functionsp groups
2010/12/8
Time and space complexities are the main properties of algorithms. Their counterparts in Group Theory are the Dehn and filling length (or space) functions of finitely presented groups. In this paper, ...
On some characterizations of ruled surface of a closed timelike curve in dual Lorentzian space
Timelike dual curve ruled surface Lorentzian space dual num-bers
2010/12/6
In this paper, we investigate the relations between the pitch, the angle of pitch and drall of parallel ruled surface of a closed curve in dual Lorentzian space.
What is a space? Computations in emergent algebras and the front end visual system
decorated braids quandles emergent algebras dilatation structures
2010/12/13
With the help of link diagrams with decorated crossings, I explain computations in emergent algebras, introduced in [6], as the kind of com-putations done in the front end visual system.
Exactness of the Fock space representation of the q-commutation relations
Exactness Fock space representation q-commutation relations
2010/11/29
We show that for all q in the interval (−1, 1), the Fock repre-sentation of the q-commutation relations can be unitarily embedded into the Fock representation of the extended Cuntz algebra. In p...
Duality for distributive space
Duality theory domain theory quantale-enriched category ultrafilter monad module cocompleteness
2010/12/9
The main source of inspiration for the present paper is the work of R. Rosebrugh and R.J. Wood on constructive complete distributive lattices where the authors employ elegantly the concepts of adjunct...
