Extremal K-(s,K-t)-free bipartite graphs
(Association DMTCS, 2008)
In this paper new exact values of the Zarankiewicz function z(m, n; s, t) are obtained assuming certain requirements on the parameters. Moreover, all the corresponding extremal graphs are characterized. Finally, an extension ...

Entanglement in eight-qubit graph states
(Elsevier, 2009)
Any 8-qubit graph state belongs to one of the 101 equivalence classes under local unitary operations within the Clifford group. For each of these classes we obtain a representative which requires the minimum number of ...

On partitions with K corners not containing the staircase with one more corner
(Elsevier, 2022)
We give three proofs of the following result conjectured by Carriegos, De Castro-García and Muñoz Castañeda in their work on enumeration of control systems: when ( k+1 2 ) ≤ n < ( k+2 2 ) , there are as many ...

Weighted Hardy inequalities, real interpolation methods and vector measures
(Springer, 2014)
We analyze the relationship of the Ariño–Muckenhoupt weights with the K - spaces obtained when the real interpolation method defined by a parameter function is applied to the pairs (L 1 , L∞) and (L 1,∞, L∞) of function ...

Multi-objective integration of timetables, vehicle schedules and user routings in a transit network
(Elsevier, 2017)
The Transit Network Timetabling and Scheduling Problem (TNTSP) aims at determining anoptimal timetable for each line of a transit network by establishing departure and arrivaltimes at each station and allocating a vehicle ...

Modelling and planning public cultural schedules for efficient use of resources
(Elsevier, 2015)
This paper addresses a decision making problem concerning the planning of cultural schedules. The model maximizes the overall welfare of the entire system by integrating the different parties involved in the process (artistic ...

Geometric Objects and Cohomology Operations
(Cornell University, 2012)
Cohomology operations (including the cohomology ring) of a geometric object are finer algebraic invariants than the homology of it. In the literature, there exist various algorithms for computing the homology groups of ...

On the r-dynamic coloring of the direct product of a path with either a complete graph or a wheel graph
(AIMS Press, 2021)
In this paper, it is explicitly determined the r-dynamic chromatic number of the direct product of any given path with either a complete graph or a wheel graph. Illustrative examples are shown for each one of the cases ...

Optimal extensions for positive order continuous operators on Banach functions spaces
(Cambridge University Press, 2014)
In this paper we give conditions under which a positive order continuous operator T defined on a Banach function space can be extended, preserving the order continuity in a certain optimal way. The optimal domain for T ...

Cheeger sets for rotationally symmetric planar convex bodies
(Springer, 2022)
In this note we obtain some properties of the Cheeger set CΩ associated to a k-rotationally symmetric planar convex body Ω. More precisely, we prove that CΩ is also k-rotationally symmetric and that the boundary of CΩ ...
