This short review article discusses the concavity method, one of most effective ways to deal with parabolic equations unbounded solutions in finite time. If solution ceases exist for some time, we say it blows up. The or its derivatives become singular depending on equation. We focus situations where becomes and our objective is key blowup theory papers utilising method.

Quantitative genetics provides one of the most important frameworks in which evolutionary biology and evolution can be studied. The primary goals of this field of study include the attempts to understand the history of selection that has resulted in the multiple phenotypic traits we observe today, and to predict the future trajectory of the multiple traits. Within quantitative genetics it is th...

Enduring is offered as supplement to existing slow cognate such ‘everyday’, banal′, ‘chronic’ offering f...

The notion of persistency, based on the rule "no action can disable another one" is one of the classical notions in concurrency theory. We recall two ways of generalization of this notion: the first is "no action can kill another one" and the second "no action can kill another enabled one". Afterwards we present an infinite hierarchy of computations in which one action disables another one for ...
