Galileon cosmologies are used for modelling of the late time cosmic acceleration. These are the slides from the seminar, which I held in CEICO in Czech Academy of Sciences 3.5.2018.

## My contribution at the 38th Winter school of geometry and physics in Srni

Galileon gravities is one approach to modified gravities. I use it in the context of cosmology in the proof of viability of these models.

## Introduction to applied functional analysis

Mathematical apparatus of Quantum Mechanics (QM) is formulated in the language of functional analysis. I made here a brief introduction to basic definitions and theorems, which are used in foundations of QM: Functional1, Functional2, Functional3, Functional4, Functional5

## My preparation for the concert 29.4.2018

I reccorded yesterday my intepretation of two Scriabin’s composition’s op.11, no.1 and op.11, no.5.

## Gravitational waves from Inflation

There were produced gravitational waves during the cosmological inflation epoch in the evolution of the Universe. First step for obtaining the spectrum is to do the perturbation of action, which composes from Einstein-Hilbert action and the action for scalar field.

## Some of my reccordings

There are my reccordings of A.N.Scriabin, F.Chopin, T.Yoshimatzu and myself: A.Scriabin – Etude op.42, no.4; A.Scriabin – Etude op.8, no.12; A.Scriabin – Prelude op.11, no.4; A.Scriabin – Prelude op.11, no.6; A.Scriabin – Prelude op.13, no.1; F.Chopin – Etude op.25, no.1, T.Yoshimatzu – Prelude to little spring, J.N. – Landing (2011)

## Concert cycle Classical Prague

We began the artistic project Classical Prague in 2015. The preparation for the serie was in Teplice, 30th March 2015. The interprets at this concert were Markéta Janoušková, Jan Novák and Andrea Vavrušová. We played in the Spa Hotel Beethoven.

The next two concerts were 17.10.2015 in evangelical church By Salvator and 1.11.2015 in church Svatý Jan na Prádle in Prague. The interprets were members of Ensemble Sporck: Lukáš Vytlačil, Lukáš Vendl, Alena Hönigová a Dora Pavlíková

Third concert was in Jan Deyl Conservatory in Prague. The artists were Adam Stráňavský, Jan Novák and Martin Kasík. It was 14.11.2015.

Fourth concert was also in Jan Deyl Conservatory 12.3.2015. The interprets were Adam Stráňavský, Jana Ivanecká, Jan Pech, Jan Novák a Pavel Voráček.

The last event was in Muzeum of Antonín Dvořák 25.6.2016. There played Pavel Voráček, Anna Rheingans and Jan Novák.

We prepare for this season 2 concerts. The first concert will be 15.10. 2017. We would like to invite You to this event.

## My lecture at the Indian summer school in Prague in 2017 about gravitational waves

One of the predictions of General Relativity are the gravitational waves. It was announced in February 2016 that the gravitational waves were finally observed for the first time in the history. It means that we obtain completely new window for the observation of the Universe. Before that event we observed the Universe almost only in electromagnetic radiation. But we have only theoretical models, what happened in the first second of the evolution of the Universe, because we are not able to detect any radiation from this epoch of evolution. But if we are able to detect primordial gravitational waves, this situation will change. Gravitational waves were already observed at LIGO and VIRGO terrestrial observatories. People prepare so called LISA observatory in space, it will be prepared for launch around 2029. And the next generation of observatories are BBO, which will be already able to detect primordial gravitational waves. I try to explain in this lecture, how we describe gravitational waves in modified gravities.

## My lecture in Benasque in 2014 at the workshop Modern Cosmology: Early Universe, CMB and LSS (section for doctoral students)

One of the biggest puzzles of modern cosmology is the accelerated expansion of the Universe, which was observed at the beginning of the 21st century. One of the possibilities, how to obtain a model, is to add the cosmological constant into the Einstein equations. Second possibility is to change the theory of gravity. There are many ways, how to do it. We were investigating so called f(R)-theories. General Relativity is one example of these theories for f(R) = R. Here is my talk.

## Popularization lecture for high school students ( Gymnasium Nad Alejí in 2012)

It was announced a result in 2012 that people measured neutrinos, which had the velocity bigger than the velocity of light. I tried to explain, why it was impossible to have such tachyons in Nature, so there had to be a mistake in the experiment. And really, there was an error in the experimental setting. Here are all slides in Czech (pictures are taken from web).
