Preprint typeset in JHEP style - HYPER VERSIONL ectures on String TheoryGleb ArutyunovaaInstitute for Theoretical Physics and Spinoza Institute, Utrecht University3508 TD Utrecht, The NetherlandsAbstract:The course covers the basic concepts of modern String Theory . Thisincludes covariant and light-cone quantisation of bosonic and fermionic strings,geometry and topology of String world-sheets, vertex operators and String scatteringamplitudes, world-sheet and space-time supersymmetries, elements of conformalfield Theory , Green-Schwarz superstrings, strings in curved backgrounds, low-energyeffective actions, D-brane Introduction to the remarks22. Relativistic particle83.
If one tries to construct the quantum mechanics of relativistic strings one finds that mathematically consistent theory exists if and only if the dimension of space-time where string propagates is 26.
