For example, the minimal 2-mer in the string ABC is AB and the minimal 4-mer in the string abracadabra is abra. In this context, the minimal $l$-mer is called a minimizer, and we'll call such a partitioning sc...

The question of existence of aperiodic monotiles stems from a weaker question, which formed part of Hilbert’s eighteenth problem: Does there exist a polyhed...

# Definition:Standard Number Field ## Definition The standard number fields are the following sets of numbers: The rational numbers: $\Q = \set {p / q: p, q \in \Z, q \ne 0}$ The real numbers: $\R = \set {x: x = \sequence {s_n} }$ where $\sequence {s_n}$ is a Cauchy sequence in $\Q$ The complex numbers: $\C = \set {...

# Formation of angle by Rotation The amount of rotation of a line from its initial position to final position is called an angle formed by rotation. ## Example A straight line can make an angle geometrically by moving from its initial position to final position. $\overrightarrow{RS}$ is a ray and it is rotated to n...

# Multiplying the matrices Problems and solutions In mathematics, the matrices are involved in multiplication. It is not actually possible to multiply a matrix by a matrix directly because there is a systematic procedure to multiply the matrices. So, let’s learn how to multiply the matrices mathematically with differe...

# Interesting mathematical documentaries I am looking for mathematical documentaries, both technical and non-technical. They should be "interesting" in that they present either actual mathematics, mathematicians or history of mathematics. I am in charge of nourishing our departmental math library (PUCV) and I would li...
