The strong invariance principle (SIP) is proved for a superposition of random processes $S(N(t))$ under rather general assumptions on $S(t)$ and $N(t)$. As a consequence, a number of SIP-type results are obtained for random sums and used to investigate their rate of growth and fluctuation of increments.
Keywords: Invariance principle, randomly stopped process, Lévy process, renewal process, stable process, stationary sequences, risk process, rate of growth.
