Decomposing numerical ranges along with spectral sets
This note is to indicate the new sphere of applicability of the method
developed by Mlak as well as by the author. Restoring those ideas is summoned
by current developments concerning -spectral sets on numerical ranges
On the number of branches of real curve singularities
There is presented a method for computing the number of branches of a real
analytic curve germ from to , where m is greater or equal to n,
having a singular point at the origin, and the number of half--branches of the
set of double points of an analytic germ from to
