Know Your Phish: Novel Techniques for Detecting Phishing Sites and their Targets
Samuel Marchal, Kalle Saari, Nidhi Singh +1
Phishing is a major problem on the Web. Despite the significant attention it has received over the years, there has been no definitive solution. While the state-of-the-art solution…
Suffix conjugates for a class of morphic subshifts
James D. Currie, Narad Rampersad, Kalle Saari
Let A be a finite alphabet and f: A^* --> A^* be a morphism with an iterative fixed point f^ω(α), where α is in A. Consider the subshift (X, T), where X is the shift orbit closure…
Extremal words in morphic subshifts
James D. Currie, Narad Rampersad, Kalle Saari +1
Given an infinite word X over an alphabet A a letter b occurring in X, and a total order σon A, we call the smallest word with respect to σstarting with b in the shift orbit closur…
Primitive Words and Lyndon Words in Automatic and Linearly Recurrent Sequences
Daniel Goc, Kalle Saari, Jeffrey Shallit
We investigate questions related to the presence of primitive words and Lyndon words in automatic and linearly recurrent sequences. We show that the Lyndon factorization of a k-aut…
Lyndon words and Fibonacci numbers
Kalle Saari
It is a fundamental property of non-letter Lyndon words that they can be expressed as a concatenation of two shorter Lyndon words. This leads to a naive lower bound log_{2}(n)} + 1…
A new geometric approach to Sturmian words
Kaisa Matomäki, Kalle Saari
We introduce a new geometric approach to Sturmian words by means of a mapping that associates certain lines in the n x n -grid and sets of finite Sturmian words of length n. Using…
