On a linear combination of some expressions in the theory of the univalent functions
(Springer-Verlag, 1975-12)
Let H (α) denote the class of regular functions f(z) normalized so that f (0)=0 and f′ (0)=1 and satisfying in the unit disc E the condition 0$$]]> for fixed α. It is known that H (0) is a particular class NW of close-to-convex ...
Invariant currents on limit sets
(Birkhäuser Verlag; Birkhäuser Verlag, Basel, ; Springer Science+Business Media, 2000-07)
We relate the L 2 -cohomology of a complete hyperbolic manifold to the invariant currents on its limit set.
On the Betti numbers of semialgebraic sets defined by few quadratic inequalities
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-06)
Non-Existence of Black Hole Solutions¶for a Spherically Symmetric, Static Einstein–Dirac–Maxwell System
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-08)
We consider for j =½, … a spherically symmetric, static system of (2 j +1) Dirac particles, each having total angular momentum j . The Dirac particles interact via a classical gravitational and electromagnetic field.
Quasi-Varieties, Congruences, and Generalized Dowling Lattices
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 1995-10)
Dowling lattices and their generalizations introduced by Hanlon are interpreted as lattices of congruences associated to certain quasi-varieties of sets with group actions. This interpretation leads, by a simple application ...
On exponentiation of G-sets
(Elsevier, 1994-12-25)
We show that Joyal's rule of signs in combinatorics arises naturally from Dress's concept of exponentiation of virtual G-sets. We also show that two finite G-sets admit a G-equivariant bijection between their power sets ...
