    "abstract": "The theories defined by Lagrangians containing second time derivative are\nconsidered. It is shown that if the second derivatives enter only the terms\nmultiplied by coupling constant one can consistently define the perturbative\nsector via Dirac procedure. The possibility of introducing standard canonical\nvariables is analysed in detail. The ambiguities in quantization procedure are\npointed out.",
