Density estimates for -impassable lattices of balls and general convex bodies in
E. Makai, H. Martini
G. Fejes Tóth posed the following problem: Determine the infimum of the densities of the lattices of closed balls in $\bR^n$ such that each affine -subspace …
Weak and strong structures and the property for generalized topological spaces
E. Makai, E. Peyghan, B. Samadi
We investigate weak and strong structures for generalized topological spaces, among others products, sums, subspaces, quotients, and the complete lattice of generalized topologies…
Pairs of convex bodies in , and , with symmetric intersections of their congruent copies
J. Jerónimo-Castro, E. Makai
High proved the following theorem. If the intersections of any two congruent copies of a plane convex body are centrally symmetric, then this body is a circle. In our paper we exte…
Nice connecting paths in connected components of sets of algebraic elements in a Banach algebra
E. Makai, Jaroslav Zemánek
Generalizing earlier results about the set of idempotents in a Banach algebra, or of self-adjoint idempotents in a -algebra, we announce constructions of nice connecting paths…
