In every mythological story, a quest for immortality and eternality depicts man’s inner fervor for unity with gods and the supreme power. Man seeks full immersion in life and longs for immortality at the same time. In other words, he wants to live both in time and in eternity. The desire for eternity in man shows his ceaseless struggle with time, and even more so an intense fight with death to ...

We study the twisted Alexander invariants of fibred knots. We establish necessary conditions on the twisted Alexander invariants for a knot to be fibred, and develop a practical method to compute the twisted Alexander invariants from the homotopy type of a monodromy. It is illustrated that the twisted Alexander invariants carry more information on fibredness than the classical Alexander invaria...

As a former student of Professor Ostrowski—one of his last— I am delighted to recall here the life and work of one of the great mathematicians of the 20th century. Needless to say that, in view of Ostrowski’s immense and vastly diverse mathematical legacy, this can be done only in a most summary fashion. Further literature on Ostrowski can be found in some of the references at the end of this a...

Cluster Analysis for Large Scale Gene Expression Studies High throughput gene expression analysis is becoming more and more important in many areas of biomedical research. cDNA microarray technology is one very promising approach for high throughput analysis and provides the opportunity to study gene expression patterns on a genomic scale. Thousands or even tens of thousands of genes can be spo...
