Coxeter group quiver mutation cluster theory exchange graph
2012/4/30
Let Q be an acyclic quiver and s be a sequence s with elements in the vertex set Q_0. We describe a sequence of simple (backward) tilting in the bounded derived category D(Q), starting from the standa...
If K is a knot or link in R3 and S R3 is a smoothly embedded 2-sphere meeting K transversely in 4-points, then one can form a new knot or link K′ as follows. One cuts R3 along S and then glues the t...
We study ‘silting mutaion’ for self-injective algebras. In particular we focus on ‘tilting
mutation’ and show that iterated irreducible ‘silting mutation’ transitively act on the set of silting objec...
On the Impact of Mutation-Selection Balance on the Runtime of Evolutionary Algorithms
Impact of Mutation-Selection Balance Runtime of Evolutionary Algorithms
2010/12/15
The interplay between mutation and selection plays a fundamental role in the behaviour of evolutionary algorithms (EAs). However, this inter-play is still not completely understood.
Mutation classes of skew-symmetrizable 3x3 matrices
Mutation classes skew-symmetrizable 3x3 matrices
2010/12/15
Mutation of skew-symmetrizable matrices is a fundamental oper-ation that first arised in Fomin-Zelevinsky’s theory of cluster algebras; it also appears naturally in many different areas of mathematics...
Species abundance distributions in neutral models with immigration or mutation and general lifetimes
Species abundance distribution Crump–Mode–Jagers process splitting tree branching process
2010/9/2
We consider a general, neutral, dynamical model of biodiversity. Individuals have i.i.d.
lifetime durations, which are not necessarily exponentially distributed, and each individual
gives birth inde...
Graded mutation in cluster categories coming from hereditary categories with a tilting object
Graded mutation cluster categories hereditary categories tilting object
2010/9/1
We present a graded mutation rule for quivers of clustertilted algebras. Furthermore, we give a technique to recover a clustertilting object from its graded quiver in the cluster category of cohX.
We define tilting mutations of symmetric algebras as the endomorphism algebras of Okuyama-Rickard complexes. For Brauer tree algebras, we give an explicit description of the change of
Brauer trees un...
Mutation-Periodic Quivers, Integrable Maps and Associated Poisson Algebras
Integrable Maps Associated Poisson Algebras
2010/3/20
We consider a class of map, recently derived in the context of cluster mutation. In this paper we start with a brief review of the quiver context, but then move onto a discussion of a related Poisson ...
Evolutionary Programming Based on Non-uniform Mutation
Evolutionary programming genetic algorithm non-uniform mutation global optimization probability convergence theoretical analysis
2008/9/9
A new evolutionary programming algorithm (NEP) using the non-uniform mutation operator instead of Gaussian or Cauchy mutation operators is proposed. NEP has the merits of \long jumps" of the Cauchy mu...
