Summary: My study is related to waves and oscillations in the solar atmosphere. Studying physical processes on the sun is important for many reasons. First and most important reason is that the very life on the Earth is completely dependent on the sun. Studying the sun will help us to increase the reliability of the weather and climate forecast, as well as to predict conditions in the interplanetary space near the Earth. To know this conditions is important for radio communication, for work of electronic devices on the ground, and for manned and unmanned space missions. The second reason for studying the sun is that it is the nearest star. Hence, studying the sun we can also learn a lot about the general physical processes on stars. This, in turn, will help us to understand better the general processes in the universe, its origin and evolution. Large part of my research is devoted to a new and fast developing branch of solar physics called solar atmospheric seismology. Its aim is to obtain information about conditions in the solar atmosphere from observation of waves and oscillations there. Solar atmospheric seismology greatly benefits from recent space missions. Among its most important achievements are the determination of the magnetic field strength and the atmospheric scale height in the solar corona. Better knowledge of conditions in the solar atmosphere will help us to advance the theory of solar wind which influences very much the near Earth space environment.
