Petar Popivanov - This talk deals with several classical and more modern results from the theory of primes and is devoted to a larger audience. A short survey is given and almost primes of order two are discussed too. Polynomials with integer coefficients are considered from the point of view of their composite and prime functional values. Exponential type functions mapping N into the set of primes are also constructed. В този доклад, предназначен за по-широка аудитория,...

Математика и музика (от Питагор до Бах и до наши дни) Mathematics and Music (from Pythagoras through Bach till the Present Time)

Димков, Георги (2011)

Union of Bulgarian Mathematicians

Similarity:

Georgi Dimkov - Looking at the performance of a violonist we perceive that the four strings of the instrument produces tones different pitches. It is clear that the artist presses the strings on special places and that changes the pitch. These places are determined practically by the musicians. Is it possible to determine these places theoretically, from some abstract point of view? After the legend the first successive investigations in this field were done by Pythagoras. The development...

Similarity:

Stojanka Valcheva, Vladimir Todorov - In the present talk we discuss some problems that arise out of the limiting the time designed for teaching Mathematics in the secondary school in Bulgaria. Средствата и “енергията”, които се отделят през последните години за преподаване на “нехуманитарни науки” за съжаление са нерастяща функция на времето и това изглежа е тендеция не само в България. Ето защо според нас е важно да се усилва и узаконява така наречената “извънкласна” форма...
