we observed in our previous paper that all the complex structures on four-dimensional compact solvmanifolds are left-invariant. The main purpose of this note is to give an example of a six-dimensional compact solvmanifold which admits a continuous family of non-leftinvariant complex structures. We also determine all three-dimensional compact complex-homogeneous pseudo-Kähler solvmanifolds.
A family of 2א0 Borel ideals on a compact lattice are constructed such that no two quotient lattices by ideals from this family are isomorphic.
Medical research and clinical trials are often based on hypotheses that were observed from clinical practice with noticeable evidence. Forming clinically significant hypotheses will greatly benefit the success of clinical research and ensure both external and internal validity of the trial. In this talk, I will introduce a knowledge discovery approach to automatically identify populations of su...
One of the most important aspects of the (statistical) analysis of imprecise data is the usage of a suitable distance on the family of all compact, convex fuzzy sets, which is not too hard to calculate and which reflects the intuitive meaning of fuzzy sets. On the basis of expressing the metric of Bertoluzza et al. (1995) in terms of the mid points and spreads of the corresponding intervals we ...
A family of probability measures on the unit ball in R generates a family of generalized Steiner (GS-)points for every convex compact set in R. Such a ”rich” family of probability measures determines a representation of a convex compact set by GS-points. In this way, a representation of a setvalued map with convex compact images is constructed by GS-selections (which are defined by the GS-point...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
In this paper, we study the number of compact sets needed in an infinite family of convex sets with a local intersection structure to imply a bound on its piercing number, answering a conjecture of Erdős and Grünbaum. Namely, if in an infinite family of convex sets in Rd we know that out of every p there are q which are intersecting, we determine if having some compact sets implies a bound on t...
