Orness For Idempotent Aggregation Functions
(MDPI, 2017-09-20)
Aggregation functions are mathematical operators that merge given data in order to obtain a global value that preserves the information given by the data as much as possible. In most practical applications, this value is ...
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 ...
An isoperimetric-type inequality for electrostatic shell interactions for Dirac operators
(Springer Nature, 2015-10-17)
Abstract: In this article we investigate spectral properties of the coupling H +Vλ, where
H = −iα ·∇ +mβ is the free Dirac operator in R3 , m > 0 and Vλ is an electrostatic shell
potential (which depends on a parameter ...
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 ...
An efficient evolutionary algorithm for the orienteering problem
(Elsevier, 2017-09-06)
This paper deals with the Orienteering Problem, which is a routing problem. In the Orienteering
Problem each node has a profit assigned and the goal is to find the route that maximizes the total
collected profit subject ...
Hedgehog frames and a cardinal extension of normality
(Elsevier, 2019-08-23)
The hedgehog metric topology is presented here in a pointfree form, by specifying its generators and relations. This allows us to deal with the pointfree version of continuous (metric) hedgehog-valued functions that arises ...
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 ...
Transporting cohomology in Lazard Correspondence
(World Scientific, 2016-07-29)
Lazard correspondence provides an isomorphism of categories between finitely generated nilpotent pro-p
groups of nilpotency class smaller than p and finitely generated nilpotent Z_p-Lie algebras of nilpotency class smaller ...
On the MIT Bag Model in the Non- relativistic Limit
(Springer, 2017-06-12)
This paper is devoted to the spectral investigation of the MIT bag model, that is, the Dirac operator on a smooth and bounded domain of R^3 with certain boundary conditions. When the mass m goes to infinity, we provide ...
Time consistent expected mean-variance in multistage stochastic quadratic optimization: a model and a matheuristic
(Springer, 2019)
In this paper, we present a multistage time consistent Expected Conditional Risk Measure for minimizing a linear combination of the expected mean and the expected variance, so-called Expected Mean-Variance. The model is ...
