چکیده

of irreducible complex projective plane curves of degree n with d nodes and no other singularities. The problem is discussed in classical literature, as well as in [1, Sect. 1], [2, p. 219], [3, Sect. 2], etc. The naive compactification of Vn,d , namely V n,d ⊂ P N , has very complicated singularities. In particular, V n,d is not unibranch. One can construct a unibranch compactification as follows. For d ≥ 1, let

UNIVERSAL COMPACTIFICATIONS OF TRANSFORMATION SEMIGROUPS

We extend the notion of semigroup compactification to the class of transformation semigroups, and determine the compactifications which are universal with respect to some topological properties.

About remainders in compactifications of paratopological groups

In this paper‎, ‎we prove a dichotomy theorem for remainders in‎ ‎compactifications of paratopological groups‎: ‎every remainder of a ‎paratopological group $G$ is either Lindel"{o}f and meager or‎ ‎Baire‎. Furthermore, ‎we give a negative answer to a question posed in [D‎. ‎Basile and A‎. ‎Bella‎, ‎About remainders in compactifications of homogeneous spaces‎, ‎Comment‎. ‎Math‎. ‎Univ‎. ‎Caroli...

Lattice of compactifications of a topological group

We show that the lattice of compactifications of a topological group $G$ is a complete lattice which is isomorphic to the lattice of all closed normal subgroups of the Bohr compactification $bG$ of $G$. The correspondence defines a contravariant functor from the category of topological groups to the category of complete lattices. Some properties of the compactification lattice of a topological ...

Alternate Compactifications of Moduli Spaces of Curves

We give an informal survey, emphasizing examples and open problems, of two interconnected research programs in moduli of curves: the systematic classification of modular compactifications of Mg,n, and the study of Mori chamber decompositions of Mg,n.
