We study center power with respect to circles derived from Poncelet 3-periodics (triangles) in a generic pair of ellipses as well as loci of their triangle centers. We show that (i) for any concentric pair, the power of the center with respect to eit

We employ the barycentric coordinate system to evaluate the inertia tensor of an arbitrary triangular plate of uniform mass distribution. We find that the physical quantities involving the computation are expressed in terms of a single master integra

We research triangle cubics and conics in classical geometry with elements of projective geometry. In recent years, N.J. Wildberger has actively dealt with this topic using an algebraic perspective. Triangle conics were also studied in detail by H.M.

ON THE CLASSIFICATION OF THE CLASS OF QUADRATIC OPERATORS GIVEN IN ONE AND TWO DIMENSIONAL SIMPLEXES
The article describes general information about one- and two-dimensional simplexes and their properties. In addition, classifications of quadratic operators defined in these simplexes, necessary and sufficient conditions for being surjective and dual

The paper aims at introducing novel distance measures for the intuitionistic fuzzy set (IFS) to discuss the decision-making problems. The current work exploits four different notions of centers, namely centroid, orthocenter, circumcenter and incenter

Inverting the vertices of elliptic billiard N-periodics with respect to a circle centered on one focus yields a new "focus-inversive" family inscribed in Pascal's Lima\c{c}on. The following are some of its surprising invariants: (i) perimeter, (ii) s

Points in the plane of a given triangle whose trilinear distances form a constant product gather on a planar cubic curve. All these cubics constitute a pencil of cubics in which the three-fold ideal line of the triangle plane and the three side lines
