Journal of Algorithms, 1991 A k-clustering of a given set of points in the plane is a partition of the points into k subsets ("cluster"). For any fixed k, we can find a k-clustering which minimizes any monotone function of the diameters or the radii of the clusters in polynomial time. The algorithm is based on the fact that any two clusters in an optimal solution can be separated

Algorithms for representing positive odd integers as the sum of arithmetic progressions [PDF]
Notes on Number Theory and Discrete MathematicsThis paper delves into the historical and recent developments in this area of mathematical inquiry, tracing the evolution from Wheatstone's representation of powers of an integer as sums of arithmetic progressions to extensions of Sylvester's Theorem ...

Decision-Making Approach under Pythagorean Fuzzy Yager Weighted Operators
Mathematics, 2020 In fuzzy set theory, t-norms and t-conorms are fundamental binary operators. Yager proposed respective parametric families of both t-norms and t-conorms. In this paper, we apply these operators for the analysis of Pythagorean fuzzy sets. For this purpose,

Classification lattices are geometric for complete atomistic lattices
Open Mathematics, 2017 We characterize complete atomistic lattices whose classification lattices are geometric. This implies an proper solution to a problem raised by S. Radeleczki in 2002.

Studia LogicaAbstract It is a well-known fact that although the poset of open sets of a topological space is a Heyting algebra, its Heyting implication is not necessarily stable under the inverse image of continuous functions and hence is not a geometric concept.

International Mathematics Research NoticesAbstract We prove that the derived direct image of the constant sheaf with field coefficients under any proper map with smooth source contains a canonical summand. This summand, which we call the geometric extension, only depends on the generic fibre. For resolutions we get a canonical extension of the constant sheaf.
