CALE: Learning by Example in Mathematics with Applets in Mathematical Computational Packages
(MDPI, 2018-10-28)
In this work we present a methodology of “learning by example” assisted by computers in the study of mathematics. We propose the use of mathematical computational packages to program applets aimed to solve mathematical ...
Invariant surfaces with generalized elastic profile curves
(2018-10-25)
En esta memoria estamos principalmente interesados en estudiar la conexión entre las curvas críticas para energías de tipo elásticas adecuadas (lo que posteriormente llamaremos curvas elásticas generalizadas) y las supercies ...
An extension of the fuzzy unit interval to a tensor product with completely distributive first factor
(Elsevier, 2018-07-10)
The original Hutton interval I (L) can algebraically be identified with the tensor product I ⊗ L of the real unit interval I and a complete lattice L. Due to this, the tensor product M ⊗ L with M a completely distributive ...
Cohomology of p-groups of nilpotency class smaller than p
(De Gruyter, 2018-01-17)
Let p be a prime number, let d be an integer and let G be a d-generated finite p-group of nilpotency class smaller than p. Then the number of possible isomorphism types for the mod p cohomology algebra H^∗(G;F_p) is bounded ...
Estimating Attraction Basin Sizes of Combinatorial Optimization Problems
(Springer, 2018-07-20)
[EN]Given a particular instance of a combinatorial optimization problem, the knowledge about the attraction basin sizes can help to analyze the difficulty encountered by local search algorithms while solving it. As calculating ...
Pro-C congruence properties for groups of rooted tree automorphisms
(Springer, 2018-12-13)
We propose a generalisation of the congruence subgroup problem for groups acting on rooted trees.
Instead of only comparing the profinite completion to that given by level stabilizers, we also compare pro-C completions ...
Some characterizations of the tensor product of complete lattices with applications to quantales
(Springer, 2018-09-17)
This paper examines tensor products of complete lattices in which one factor is com- pletely distributive. At least five characterizations of complete distributivity involving tensor products of complete lattices are given, ...
